How to Select The Correct Accuride Drawer Slide?

How to Choose your Load rating

When first selecting the correct drawer slide, also known as ball bearing slides, for your application you must consider the correct amount of force that you are loading onto the application which is supported by the slide.

Measurements are taken between and at the midpoint of the drawer member and are given in KG.

We are a proud distributor of Accuride Drawer Slides because of their quality and reputation within the industry. As result, Accuride slides have a 100% static safety factor in the extended position.

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. See our FAQ for a list of our slides that can be horizontally mounted.

External Factors AFFECTING choosing the correct load rating

Shock/vibration

Subjecting slides to shock and vibration may adversely affect their performance. Applications that are subject to these conditions should be tested to evaluate the effect on slide performance. If conditions are severe, select a heavier-duty slide.

Application factors

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.

Environmental factors

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°C and 70°C.

Please note: 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. if you require further support please contact us and our team will be happy to help.

Slide extension or travel

Extension and travel refers to how far the drawer extends from the cabinet.

75% extension: drawer opens approximately 75% of the total length of the slide
100% extension: drawer opens the same amount as the slide length
100+% extension: over-travel is achieved. The drawer opens in excess of the slide length
Most full (100%) extension slides have nominal over-travel.
Linear motion slides move in a straight line and within the slide’s own length
Two-way travel - provides access from both sides of the drawer

Side space

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.

Slide profiles

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.

Determine Special Features you may require

Disconnect allows simple connect or disconnect from the slide assembly

Lever - disconnect is achieved by releasing an internal lever and by pulling the drawer firmly through the resistance of the ball retainer
Push latch - a latch is pressed to release the drawer and disconnect is achieved by pulling the drawer firmly through the resistance of the ball retainer

Locks hold the slide either closed or open and a lever must be actuated to move the slide

Hold-in and hold-out (DO) keeps the slide open or closed until the extra force is applied

Self-close (SC) slides include a spring attachment designed to close the slide and prevent bouncing back

Dampened soft close (EC) slows the closing action for a controlled and smooth operation

Touch release (TR) slides open with pressure to the front of the slide

Mounting options, for example, bayonets and brackets

Cycle tests

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.

Installation

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.

Mounting holes

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

Length

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.

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.
