Lubricant is the first thing that comes to mind when you start using industrial machinery as needed for unsurpassed performance in critical high-temperature applications.
Molygraph has been developing lubricants using the most advanced chemistries available. If Molygraph isn’t a part of your equipment, you should consider it… Or rather use it. We all know that industrial chains suffer more from bad lubrication rather than workload. Regular maintenance and lubrication are preconditions for low wear and long service life of the chain drive. The maintenance and lubrication frequency, as well as the related re-lubrication, are determined by the operating conditions of the application.
Sufficient and effective lubrication increases the length of life of the chains several times over. The selection of the correct lubricant and the appropriate method of lubrication guarantee reduction of wear, protection from corrosion and optional damping characteristics.
Even though many of the low-speed chains run successfully, with little or no oil, routine lubrication on the production line greatly extends the service life of the equipment. Chain drives are required for the lubrication of the six main objectives:
• Removal of any foreign material.
• To prevent rust or damage.
• Withstand the wear and tear of the pin
• Dissipate the heat.
• Shock-absorption.
The document discusses lubricants that can provide long-term reliable lubrication for circuit breakers.

This document provides information on various power transmission elements and methods of drive, including belts, chains, gears, shafts, and other components. It discusses the components and functioning of belt drives, including different types of belts. Chain drives are described as using sprockets and links to transmit power without slip. The different types of gears are outlined, including spur gears, helical gears, bevel gears, worm gears, and rack and pinion systems. Terminology related to gears such as pitch circle, pressure angle, and modules are also defined. The document aims to explain the basic components and principles of different power transmission methods.
Mechanical Power Transmission
Electrical power transmission has replaced mechanical power transmission everywhere except very shortest distances. What is worth remembering, however, is that from the 16th century through the industrial revolution to the end of the 19th century mechanical power transmission was the norm – even for long distances.
This document discusses different types of gears including spur gears, helical gears, bevel gears, and worm gears. It provides details on the general characteristics, limitations, and advantages of each gear type. Spur gears are the most common and inexpensive but cannot change the direction of rotation. Helical gears can transmit power between non-parallel shafts and withstand higher loads than spur gears. Bevel gears are used for intersecting shafts. Worm gears allow perpendicular shafts and have self-locking meshes, but are inefficient.
Mechanical seals are used to prevent leakage between a rotating pump shaft and casing. They have two flat surfaces, one rotating with the shaft and one stationary. Proper selection of seal type, materials, and cooling method is important for long seal life. The main types are single or multi-spring seals, bellow seals, and seals that are balanced or unbalanced. Factors like pressure, temperature, fluid properties, and available space must be considered.
Gears are components that transmit rotational motion from one shaft to another. There are several types of gears according to the position of their axes, including parallel gears like spur and helical gears, intersecting gears like bevel gears, and non-parallel, non-intersecting gears like worm gears. Gear trains involve two or more gears meshing together to reduce speed and increase torque. Common gear train types are simple, compound, and planetary gear trains. Planetary gear trains are popular for automatic transmissions due to their high gear ratios.

This document provides an overview of gears and gear trains. It defines gears as toothed wheels that transmit motion between two shafts, and gear trains as combinations of two or more meshing gears. The document then discusses the types of gears based on axis position and peripheral velocity, as well as the materials and manufacturing processes used to make gears. Finally, applications of gear trains are described, including their use in differentials to allow wheels to rotate at different speeds.
This document discusses belt drives and pulleys. It defines a belt drive as using one or more continuous belts over two pulleys to transfer rotary motion between two shafts via friction. The main types of belts are flat, round, V, and timing belts. Belt drives can be open, crossed, use idler pulleys, or be compound. Applications include machinery like drilling machines, lathes, and automobiles.
A belt drive uses a looped strip of flexible material called a belt to mechanically link two or more rotating shafts. Belts are looped over pulleys to transmit power efficiently between shafts. Belts can drive pulleys in the same direction in an open belt drive, or in opposite directions in a crossed belt drive. Belts transmit power simply and economically over variable distances between non-parallel shafts while absorbing shock and reducing noise and vibration. However, belt slip and stretch can vary the speed ratio from the pulley diameter ratio.

3. It discusses the physics of arc welding including arc plasma formation, arc temperature, arc polarity, effects of magnetic fields, and arc types from different power sources.
Gears are components that transmit rotational motion between two shafts. There are several types of gears classified by the position of their shafts, including spur gears where the teeth are parallel to the axis of rotation, helical gears which are cut at an angle, and bevel gears where the shafts meet at an angle. Gears are used in many machines and mechanisms to increase torque or change the speed and direction of rotation between two shafts.

Take a look inside to see some of the key products that we stock in this category of MRO, Tools, Safety and Rig Essentials. Whether you are a rig operator or an oilfield supplier, you will find consolidating your purchases with us for the items we stock would be the right way to service your end-users requirement the quickest way!
How We Work
Imagine using a $200 a pail dope and using a $1 dope brush, the savings you have with the brush costs, you don’t realise the loss you incur with the dope as a faulty brush creates pilferage of materials, improper application of dopes and overall a total higher costs than the savings you made buying the cheap dope brush.
Keeping this logic in mind that a cheap substitute ultimately costs more in total costs, Project Sales Corp has built up a portfolio of proven good quality high performance products from India and worldwide used on-board drilling rigs. They improve reliability, reduce overall costs, downtime and provide user a peace of mind with daily essentials on the rig.
We don’t stock the quality that generally sells in the local markets, we bring in products that have proven themselves in being able to make a positive difference. That’s sums up our strategy to this core product category – The rig essentials line of Ropes, Soaps, Dopes that has contributed over $25 million of revenues in last 10 years.
The daily materials used on a rig are colloquially referred to as Rope, Soap, and Dope.
➢ Rope referred to chains and ropes used to hoist materials up to derricks and platforms
➢ Soap was used in reference to products and tools used to clean machinery, tools, the rig, and the workers themselves
➢ Dope meant the lubricants, grease, and fuel - the essential liquids that were employed to keep machinery and the rig up and running.

Project Sales Corp is pleased to introduce its Sealing Compounds range. We represent one of the most exhaustive range of Sealing Compounds from around the world that finds application in sealing steam and gas turbines, compressors, pumps, gearboxes, flanges and more.
An ideal flanged joint would consist of two, mirror-finish, perfectly flat and parallel surfaces bolted directly together to create a leak-free seal. However, manufacturing processes do not allow for perfect sealing surfaces. Most flange faces have surface irregularities that cannot be sealed without the use of some type of compressible, resilient material or a combination of materials between them to seal the fluid being transferred. This is true even for the most finely machined surfaces as a turbine flange where the surface asperities can create a leak situation.
Slung loads are dangerous. Going close to it exposes one to various injuries, pinch, crush and foot and body injuries. There is tension in the load until it rests in the final position. There are obvious chances of injuring the fingers and hands and getting too close to the red zone where a suspended dropped object could fall on the foot or body. You also expose yourself to lacerations and abrasion when the object you are trying to guide is sharp or rough.
PSC introduces the PSC Guide-it SlingGrab, a simple to use load positioning tool to manage slung loads by using the special head designed for chains and wire rope slings, webbing slings, to grab and manoeuvre the slung loads while it moves to its final position. Concept is simple - if we can keep our hands at a distance while doing tasks like guiding, positioning, pushing, pulling slung loads or doing anything to bring it to its final place – we avoid a “caught between” kind of situation and protect our hands.
Available in 4 lengths and competitively priced, you can now make it a rule, no grabbing slings by hand, always use a PSC Guide-it SlingGrab. Please see attached for more details.

Brief Description of

Molykote® Book, Published by Dow Corning GmbH, Munchen

hain drives are used to transmit forces and motion between parallel shafts.
They are used whenever spindle/shaft spacings have to be bridged which
cannot be achieved with gear wheels or with belt drives because of
unfavorable space or transmission conditions. Chain drives are preferred to as
“positive envelope drives”. One or more sprockets are “enveloped” by an endless
chain. They offer slip-free power transmission. If properly designed, they combine the
advantages of a positive belt-drive with those of a positive gear wheel drive. Any
shocks, which can endanger service reliability, are largely absorbed by chain drives,
unlike spur gears, where elastic couplings have to be used. The mechanical efficiency of
chain drives is ŋ = 0.93 to 0.99.
A varietyof types of sprocket chains are used as drive chains or load chains for power
transmissions, such as:
Heavy duty roller chains; closed pitch or precision roller chains; flat top crate conveyor
chains; ‘duplex’ or ‘triplex’ roller chains; malleable iron link chains; inverted-tooth or
silent chains.
Because of its versatility, the roller chain should be seen as the most important.
Tribotechnical Design of Chains
When lubrication is carried out with oils or greases, chains will operate in the mixed-
friction range; with power transmission takes place both via the lubricant and the solid-
body contact. For good tribological design, it is therefore important to keep wear
caused by mixed-friction as small as possible, by using suitable lubricants. The lubricant
must also meet secondary requirements relating to adhesion and oxidation resistance,
in addition to the primary requirements.

Practical Application
Various methods can be used to apply chain lubricants. This include:
Manual Application; Drip-feed application; Splash lubrication in oil bath; Forced-feed
circulatory lubrication; Oil/air lubrication (spray lubrication); dry lubrication with anti-
friction coatings.
Minimising wear using specialty lubricants
In the case of heavily loaded chains drives, high viscosities are used to minimize wear.
Molykote® provides a

one of the main criteria. Because of the greater proportion of
mixed friction, the decrease in viscosity at higher temperatures means greater wear on
pins and bushes, and considerably limits the service life of a chain drive. Mineral oils
are not used elevated temperatures since gumming (resinification) occurs as low as 120
degree C, which can affect chain flexibility. Synthetic oils with favourable viscosity-
temperature properties are therefore used at high temperature ranges.

Molykote® Technologies
Dispersions
Molykote® dispersions are finely divided solid lubricants
suspended in lubricating fluids. They are preferred where it is
necessary to apply solid lubricants in liquid form to units in
operation or to otherwise inaccessible points.
Anti-friction Molykote® anti-friction coatings are similar to a lubricating
Coatings paint and contain a select blend of molybdenum disulphide and
other solid lubricants dispersed in resinous or inorganic
binder/solvent. They cure to form a dry, solid lubricant coating
that is bonded to the surface. Dusty environment and inaccessible parts, which are
lubricated for life, are ideal applications for anti-friction coatings.
Greases Molykote® chain greases are fortified with molybdenum
disulphide to provide effective lubrication under extreme load
conditions. Molykote® grease formulations are available with
mineral oil or synthetic oils. They contain adhesion improvers, corrosion inhibitors,
solid lubricants and solvents, which assist penetration into critical areas such as link
pins.
Oils Molykote® has an extensive range of chain oils in mineral and
synthetic bases. Viscosity grades are available from 26 mm²/s to
over 4000 mm²/s. They are available in food-grade and non-
food grade formulations. Molykote® synthetic formulations contain thermally stable
oxidation inhibitors and extreme pressure additives, and combine these with their
excellent high temperature performance. They can be applied manually with brush,
spray gun, or automatic lubricators using drip, jet or spray.
Aerosols Molykote® aerosols are easy to use maintenance sprays available
for quick lubrication of inaccessible points. They combine the
Molykote® advantage of delivering solid lubricants in an easy to
use spray can with carrier oils or solvents and high performance additive formulations.
They provide excellent chain link penetration and adhesion and lubricity after
evaporation of the carrier oil or solvents.

Oil Molykote S 1500 series is a new line of high technology chain
oils introduced recently with the highest temperature resistance
and lower friction than comparable synthetic oils.
One of the effects of the temperature in a lubricant is its oxidation. The resistance of a
lubricant to oxidation can be measured by TG Analysis test. Molykote S-1502 from the
new line shows a 300% better resistance than other high quality synthetic chain oils.
Another important effect of the temperature in a lubricant is the evaporation. The
ASTM D 972/97 can measure this. The better resistance of the new Molykote chain
oils can represent a reduction of more than 600% of the evaporation.
The SRV ASTM D-5707 test measures the co-efficient of the function of a lubricant.
The new additive package of the Molykote® S-1503 and S-1504 allows a reduction of
the co-efficient of friction from a 0.10-0.12 of other competitors’ synthetic oils to 0.04.
Molykote S 1500 series of oils can be used with brush, spray gun, drop-feed oiler or
conventional metering devices, and are available in 5ltr and 20 ltr cans.

Grease/Paste Molykote P 40 is a grease paste combining the advantage of
easy application of grease with the corrosion protection and
high temperature capabilities of solid lubricant pastes. The
product is ideal for application for normal and stainless steel chains, which have
premature wear due to heavy loads and corrosion due to wet environments. Molykote
P 40 is a synthetic based product with inorganic thickener making it ideal for any grease
application chain requiring very high temperature resistance and long-term lubrication.
The base oil viscosity of the product is 900 cst at 40 degree C, and it contains adhesion
improvers which resist even splash water. Available in 400 ml spray cans and 1 kg
packing, the product is excellent lubricant for chains operating in very high
temperatures, open corrosive environments or where splash water is likely.
Oil Food-grade Molykote L-1460 FG and L-1468 FG are high performance
industrial lubricants for chain applications where H1 designation
is required for incidental food contact not to exceed 10 ppm.
These products have wide service temperature range and are available in synthetic and
semi-synthetic formulations. They help food and beverage installations reduce overall
maintenance costs by providing longer lubrication intervals and resist breakdown even
in the presence of water and steam. Molykote FG chain oils are SAE 30 grade oils with
a viscosity of 66 cst at 40 degree C. For more information on these new products,

10. Selection Matrixes
The L-E-T-S matrix represents the primary lubricant requirement relating to the reduction of
wear caused by mixed friction. In addition, secondary requirements have to be met,
depending on the application. Oxidation resistance and adhesion must be taken into account
to a greater extent in lubricant applications involving chains.

11. Hints on repair and maintenance
The service life of a chain can be increased considerably by using suitable lubricants under
different service conditions and observing the requisite relubrication periods. The principle cause
of chain failure is excessive wear, resulting from improper lubrication or inadequate maintenance.
If when checking the state of wear of the chain links, the chain has been stretched by more than
2-3% of its initial length, it must be changed, otherwise differences in pitch will be produced
between the links which can no longer be absorbed by the sprockets. Additional stresses and
friction moments are thereby generated, increasing the stress on the chain.
A very dirty chain must be cleaned, to allow penetration of the lubricant. Suitable solvents such as
1.1.1-trichlorethane or white spirit, or Dow Corning OS2 cleaner for precision chains, are used for
this purpose. After cleaning, the chain is dried with a lint free cloth.
If the chain has to be fully lubricated, it must be removed, thoroughly cleaned and then immersed
in chain greases, anti-friction coatings, high viscosity chain oils, etc to achieve complete lubricant
penetration.
If dipping process is used, the dipping process should take place in such a way that the chain
rollers are at right angles to the bottom of the dipping tank.
Synthetic chain oils have a longer life at high temperatures, have greater oxidation stability and
leave fewer combustion residues and decomposition particles.
In drip-feed, the quantity of oil dependent on chain speed should be approx. 4 to 10 drops per
minute. The quantity of oil must be increased for temperatures in excess of 60 degree C,
In case of heavily loaded chain drives, high-viscosity lubricants are used to minimize wear. In
addition, solid lubricants are used as additives.
High centrifugal forces, such as occur at pinion and sprocket (reversing points) with fast-
running chains, call for appropriate lubricant adhesion. Thin oils are thrown from the chain
much more quickly than thick oils.
