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's requirements to the key performance elements of the slide.
Slide length is measured as the longest dimension of a fully closed slide. As a rule, always use 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, approximately 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.
In general, wider drawers require a slide with a higher load rating and a cross section designed to withstand lateral stress. Consult product technical sheet for slide recommendations based on drawer widths.
There are generally two types of slide movement:
Telescoping movement occurs in stages. The drawer member extends fully and then picks up the intermediate member, pulling it to the end of the travel.
Progressive movement is a result of all slide members moving simultaneously. This type of movement provides extremely smooth, quiet movement.
The disconnect feature enables you to remove a drawer or drawer member for mounting or general purposes. There are four common types of disconnects:
Disconnect is achieved by releasing an internal lever and pulling the drawer outward, away from the cabinet.
A rail latch allows you to raise the drawer off the slide and away from the cabinet. This type of disconnect facilitates smooth movement and easy drawer removal.
No levers or latches are required to remove the drawer. Disconnect is achieved by pulling the drawer firmly through the resistance of the ball retainer.
A latch is pressed to release the drawer. Disconnect is achieved by pulling the drawer firmly though the resistance of the ball retainer.
More than one slide profile (or height) may be appropriate for a given application. Accuride provides several low-profile design options for applications in which a smaller slide profile would enhance the appearance of the completed unit.
All Accuride slides are tested a minimum of 50,000 cycles in accordance with the guidelines of applicable ANSI/BIFMA specifications, or as appropriate for some moderate use applications. See the product detail or technical sheet for specific information regarding test criteria. Thorough testing means that you can count on Accuride slides to meet industry-accepted criteria.
Our slides are rated for the dynamic (cycled) load that an 18" pair will carry without failure. This load rating decreases proportionally beyond the 18" length. In all cases, the static (resting) load capacity of each model is at least twice the load rating, providing at minimum a 100% static safety factor even when the slide is loaded to its maximum rating. Because slide performance may be affected by factors unique to a specific application, always test slides in your intended application.
For optimal slide performance, mount slides only as indicated in the catalog or on the technical sheet. Certain slides may be mounted flat under a drawer, but the resulting load rating will be at least 50% less than the load rating applicable to the same pair of slides mounted vertically on the side of the drawer. Please consult the product technical sheet for specific flat-mount load rating information.
Subjecting slides to shock and vibration may adversely affect their performance. Applications that are subject to these conditions should be tested to evaluate the affect on slide performance. If conditions are severe, select a heavier duty slide.
When installed in a drawer or cabinet that is lightweight and flexible, drawer slides can contribute to the structural rigidity of the unit. To ensure that the slide is able to provide this support, select a model with a slightly higher load rating and larger cross section than you would ordinarily need for the application.
Most slides are designed to be mounted in pairs on the sides of drawers or the moving unit. When installing the slides, exercise care to ensure that they are mounted parallel to each other, in vertical and horizontal axes.
Before mounting slides other than as designed, carefully consider any potential adverse effects on the slide and, if necessary, consult Accuride directly. For example, mounting slides flat under the drawer, rather than on the side, will lower the load rating by at least 50%, but mounting a slide high on one side and low on the other side will have little adverse effect on load rating. Be sure to evaluate the mounting scheme thoroughly and test as needed. Not all slide models may be used in flat-mount applications.
Accuride slides are designed for indoor use and should be protected from excessive moisture, chemical fumes, dirt, and corrosion. The Accuride self-cleaning ball retainer protects slide raceways by removing foreign particles between ball bearings, and the lubricant provided is sufficient for normal slide life.
Use care when applying finishing agents as the overspray may affect slide movement. Should you need to clean the slides, you can re-lubricate them with a quality grease rated "EP" for extreme pressure.
Extreme temperatures can also affect the lubricant and plastic or rubber components. Commercial drawer slides are designed to be used for extended periods in temperatures between 0 and 180 degrees Fahrenheit. For service outside normal temperature and humidity ranges, consult Accuride directly.
