All Accuride drawer slides undergo cycle tests according to the expected frequency of use. See individual slides for details on the cycle test rating. Load ratings quoted are the maximum for a pair of side mounted slides installed 450mm apart, unless otherwise stated. The load ratings will change according to the length of the slide. Mounting slides in different configurations will affect the performance and load rating, please see below. We advise clients to test slides in the intended application.
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’s 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, care should be taken to ensure that they are mounted parallel to each other, in vertical and horizontal axes. The measurements taken are between and at the midpoint of the drawer member and are given in kg.
Before mounting slides other than as designed, carefully consider any potential adverse effects on the slide.
Horizontal (flat) mounting
Horizontally (flat) mounting the slides reduces the load capacity to at least 25% of the vertical (side) mount capacity. Not all slide models can be used in flat mount applications. Be sure to evaluate the mounting scheme thoroughly and test as needed. For horizontally mounted slides look for the symbol below on the product page. Linear slides are ideal for flat mounting because the moving member is fully supported on ball bearings at all times. Below is a list of slides which can be horizontally (flat) mounted.
Drawer width and depth
In general, wider drawers require a slide with a higher load rating and a cross section designed to withstand lateral stress. Check with individual products, to see which slides are recommended for particular drawer widths and depth.
Mounting holes are indicated and dimensioned on product technical sheets. Only those holes shown with a dimension are to be used for mounting. Non-dimensioned holes are tooling holes that often vary in shape and location on slide members. Please refer to 2D CAD drawings for dimensional tolerances
Slide length is measured as the longest dimension of a fully closed slide. As a rule, always use the maximum length possible in an application.
Side space is the amount of available room between the drawer side and the cabinet or the chassis and rack. The correct side space dimension is critical for optimal movement. We recommend allowing between +0.2mm and +0.5mm over the nominal slide thickness. Some slides may need more room, but this will be stated on the individual installation guides.
Types of movement
There are generally two types of slide movement:
Telescoping movement occurring 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.
More than one slide profile (or height) may be appropriate for a given application. Accuride offers several low-profile design options for applications in which a smaller slide profile would enhance the appearance of the completed unit.
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 -17° and 70° Celsius.
