The document discusses bearings, including: - Bearings are mechanical components that allow rotation between parts and consist of rolling elements like balls or rollers. - There are several types of bearings including ball bearings, roller bearings, thrust bearings, and tapered roller thrust bearings. - Bearing life refers to the period a bearing can continue operating before failure from factors like noise, abrasion, fatigue, or damage. Proper selection, mounting, and maintenance can extend bearing life. - Relative bearing refers to the angle between an object and the forward direction of a vessel, and is used for navigation.

5. The word "bearing" incorporates the meaning of "to bear," in the
sense of "to support," and "to carry a burden." This refers to the fact
that bearings support and carry the burden of revolving axles. The
two pictures below show the most basic bearings, known as rolling
bearings.

Radial + Thrust
Bearing
Axial bearings, or thrust bearings,
are designed to withstand force in
the same direction as the shaft. ...
Radial ball bearings are designed
to withstand forces that are
perpendicular to the direction of the
shaft
Thrust Bearing
A thrust bearing is a particular type
of rotary bearing. Like other rotary
bearings they permit rotation
between parts, but they are
designed to support a high axial
load while doing this
Radial Bearing
A ball bearing in which the direction
of action of the load transmitted is
radial to the axis of the shaft

Cylindrical roller bearings are available
in a wide range of designs, series,
variants and sizes. The main design
differences are the number of roller
rows and the inner/outer ring flanges as
well as cage designs and materials.

The inner and outer ring raceways are
segments of cones, and the rollers are
tapered so that the conical surfaces of
the raceways, and the roller axes, if
projected, would all meet at a common
point on the main axis of the bearing.
This geometry makes the motion of the
cones remain coaxial, with no sliding
motion between the raceways and the
outside diameter of the rollers.

A spherical roller bearing is a rolling-
element bearing that permits rotation with
low friction and permits angular
misalignment. Typically, these bearings
support a rotating shaft in the bore of the
inner ring that may be misaligned in
respect to the outer ring. The
misalignment is possible due to the
spherical internal shape of the outer ring
and spherical rollers.

A needle roller bearing is a special type
of roller bearing which uses long, thin
cylindrical rollers resembling needles.
Ordinary roller bearings' rollers are only
slightly longer than their diameter, but
needle bearings typically have rollers
that are at least four times longer than
their diameter. Like all bearings, they are
used to reduce the friction of a rotating
surface.

25. Bearing Life
The various functions required of rolling bearings vary according to the bearing application.
These functions must be performed for a prolonged period. Even if bearings are properly
mounted and correctly operated, they will eventually fail to perform satisfactorily due to an
increase in noise and vibration, loss of running accuracy, deterioration of grease, or fatigue
flaking of the rolling surfaces. Bearing life in the broad sense of the term, is the period during
which bearings continue to operate and to satisfy their required functions. This bearing life may
be defined as noise life, abrasion life, grease life, or rolling fatigue life, depending on which one
causes loss of bearing service. Aside from the failure of bearings to function due to natural
deterioration, bearings may fail when conditions such as heat-seizure, fracture, scoring of the
rings, damage of the seals or the cage, or other damage occurs. Conditions such as these should
not be interpreted as normal bearing failure since they often occur as a result of errors in bearing
selection, improper designer manufacture of the bearing surroundings, incorrect mounting, or
insufficient maintenance.

29. Relation between
Bearing and Angle
04

30. Relation between Bearing and Angle
 Relative bearing refers to the angle between the craft's
forward direction and the location of another object. For
example, an object relative bearing of 0 degrees would be
dead ahead; an object relative bearing 180 degrees would be
behind. Bearings can be measured in mils, points or
degrees.

31. In nautical navigation the relative bearing of an object is the clockwise angle from
the heading of the vessel to a straight line drawn from the observation station on
the vessel to the object.
The relative bearing is measured with a pelorus or other optical and electronic
aids to navigation such as a periscope, sonar system, and radar systems. Since
World War II, relative bearings of such diverse point sources have been and are
calibrated carefully to one another. The United States Navy operates a special
range off Puerto Rico and another on the west coast to perform such systems
integration. Relative bearings then serve as the baseline data for converting
relative directional data into true bearings (N-S-E-W, relative to the Earth's true
geography). By contrast, Compass bearings have a varying error factor at
differing locations about the globe and are less reliable than the compensated or
true bearings.

The first modern recorded patent on ball

and iron-master Philip Vaughan. He
patented the first design for ball bearings
in 1794, which were designed to support

39. The Secrets of Proper Bearing Lubrication

At the heart of almost every industrial facility are electric motors, which
can render equipment inoperative should their rolling element bearings
fail—an occurrence more common than necessary due to strain
resulting from improper lubrication. Lubricating your motors properly is
easy, but not exactly simple. If you fail to consider all factors involved,
your equipment will be predisposed to early failure. Investing in the right
tools is a crucial part of maintaining a structured lubrication program
and addressing all factors involved.
