The document discusses sliding door guides and provides information on design factors, environmental factors, materials, and manufacturing processes for drawer slides. Some key points include: - Drawer slide length, extension (how far the drawer can open), and intended environment should be considered when choosing a slide. - Slides are generally intended for indoor use between 0-180°F and can be made of steel, stainless steel, or aluminum. - Slides are manufactured using roll forming and bending processes and then assembled. - Common mounting options for slides include side mounting, center mounting, and under mounting. Clearances needed vary by mounting type.

2. DESIGN FACTOR
• As with the selection of any system component, when choosing a slide for a
specific application, you should consider the full range of features by comparing
the project requirements to the key performance elements of the slide.
• LENGTH Slide length is measured as the longest dimension of a fully closed slide.
As a rule, always specify the maximum length allowable in the application.
• EXTENSION
Or “travel”, refers to how far the drawer extends from the cabinet.
3/4 extension Drawer opens partially, about 3/4 of the total slide length.
Full extension Drawer opens the same amount as the slide length.
Over travel Drawer opens more than the length of the slide.

3. ENVIRONMENTAL FACTOR
• Unless otherwise stated, slides are designed for indoor use and
should be protected from excessive moisture, chemical fumes, dirt,
and corrosion.
• The self-cleaning ball retainer protects slide raceways by removing
foreign particles between ball bearings, and the lubricant provided is
sufficient for normal slide life.
• Commercial drawer slides are designed to be used for extended
periods in temperatures between 0 and 180 degrees Fahrenheit.
Extreme temperatures can negatively affect the lubricant and plastic
or rubber components.

4. MATERIAL
• STEEL SLIDES:
Slide members and ball retainers are made from cold-rolled steel; ball bearings are
carburized steel.
STANDARD FINISH (C): Clear zinc electroplate
OPTIONAL FINISHES: CB - Black electroplate EW - White electrocoat CH -
Weather resistant
• STAINLESS STEEL (SS): Slide members, ball retainers, and ball bearings are
stainless steel.
• ALUMINUM (AL): Slide members are aluminum, ball retainers and bearings are
stainless steel.

5. MANUFACTURING PROCESS
• ROLL FORMING
1.JIANT BUNDLE OF ROLLED STRIP IS IS ROLL PASSED
2.WHERE FIRST BENDING FROM EDGES ,SHERAING AND PUNCHING
TAKES AT ONE INSTANCE
3. THUS STOPPER IS ATTACHED AT THE END TO STOPE THE RAW
MATERIAL AND BLANK IS CUT DOWN IN ORDER TO GET DESIRED
LENGTH OF STRIP
• THEN TWO OTHER STRIP ARE PRODUCED FOE SLIDING ACTION
• IN 1st STRIP THE BEARING IN PUNCH IN A STRIP IN ORDER TO CREATE THE
SLIDING ACTION OF STRIP AND ANOTHER STRIP TO CREATE AND
ELONGATION

6. MANUFACTURING AND ASSEMBLY

7. TYPES OF MOUNTING OF SLIDES
• Side-mount slides
sold in pairs or sets, with a slide attaching to each side of the drawer.
- Available with either a ball-bearing or roller mechanism.
- Require clearance – usually 1/2" – between the drawer slides and the sides of
the cabinet opening.
 Center-mount slides
• as single slides that, as the name suggests, mount under the center of the
drawer.
• - Available in classic wood version or with ball-bearing mechanism.
• - Required clearance depends on thickness of slide.

8. • Under-mount slides
• are ball-bearing slides that are sold in pairs. They mount to the sides of the cabinet and
connect to locking devices attached to the underside of the drawer.
• - Not visible when the drawer is open, making them a good choice if you want to
highlight your cabinetry.
• - Require less clearance between the drawer sides and the cabinet opening (usually
3/16" to 1/4" per side).
• - Require specific clearance at top and bottom of cabinet opening; drawer sides typically
can be no more than 5/8" thick.
• - Space from underside of drawer bottom to bottom of drawer sides must be 1/2".
