The answer to which is best really depends on several factors such as budget and what you want to achieve with the slide.
They come with either nylon or steel rollers and provide a reasonably stable movement with either full or partial extension.
Roller runner technology is very simple so they should present no operational problems and are good value for money.
Rollers are normally used in the ‘budget’ furniture ranges, but there are some heavier weight rollers that can be used in other movement applications and where drawer removal is an important requirement, for example tool cabinets.
The roller runners that are made to carry larger loads start to get expensive and are physically larger than the equivalent ball bearing slide.
For: Easy to fit and good value. Allow easy removal and reinsertion of drawers. Quiet.
Against: Rollers for heavier loads are much larger than their equivalent ball bearing slides and can be expensive. Full extension rollers have a tall cross section.
This gives good lateral stability and the flexibility to make the profiles larger and therefore able to carry heavier loads. They also give part, full and over travel as well as two-way travel.
For: Ball bearing telescopic slides come in a very large range of sizes suitable for many applications outside of traditional furniture drawers.
They also have many fixing options including different types of bracket or bayonet lancings. The profiles can be made from heavier gauge steel and can be stacked to give huge load carrying ability.
Ball bearing slides have a much larger range of sizes and load capacities than roller slides. For heavier loads, the ball bearing slide will be smaller and often better value than roller runners.
Against: Can be over-specified, and therefore expensive, for some applications.

This has benefits both for the assembly of the application and also for the end user. First it means that you can take the drawer member and mount it to the moving part of the application – such as a drawer, possibly in a separate part of the manufacturer’s facility. The remainder of the slide, commonly the cabinet and intermediate member, can be fixed into the cabinet. It is then a simple matter of bringing the two parts of the application back together and assembling the moving element into the cabinet, making the slide fitting and installation very easy.
Secondly, while in use, the drawer / moving element can be easily removed for maintenance, cleaning or replacement, etc. and then reinserted.
Imagine mounting a heavy piece of equipment (this is where our heavy duty slides come in) on a slide such as the 9301. With a heavy load you would not want a slide that disconnected. The last thing you need is a slide that can come apart and dump the equipment on your feet.
Also, if you are mounting something that is very wide and / or heavy, you must consider the health and safety aspects of disconnection. It is likely that you will not be able to release both of the disconnect levers and easily hold the application with both hands.
Where a medium duty slide with disconnect, such as our 3657 series (up to 124 kg) is used, you should have procedures in place to ensure the safe disconnection of heavier loads. Or simply choose non-disconnect slides. You would find it impossible to hold a fully loaded drawer in position to re-assemble the separated slide members. It is always best to factor in a two-person or mechanical procedure to assemble and disconnect the moving element of an application, especially if the full load is applied.
If in any doubt you can contact your local Accuride distributor or email our Technical Manager with your questions.
A slide with self-close will close the slide by engaging the mechanism in the rear of the cabinet member using a pin element on the drawer member. The closing action is very positive and is performed by a spring that has no damping.
Slides can have different closing forces to pull in different loads. The mechanism also acts as a hold-in, by virtue of the spring pressure holding the slide closed – preventing the slide from bouncing open.
Because the mechanism requires a spring force to pull the load closed, this will also affect the opening force; the spring rate needs to be overcome while opening the drawer. Let’s image a self-close slide on a drawer. The user will feel a resistance from the spring while opening the drawer, but this will disappear once the slide has been released from the spring.
This helps prevent the slide from slamming closed. The damper is normally positioned in the mechanism at the rear of the slide, similar to the self-close, and controls the closing action.
This mechanism also acts as a hold-in, stopping the slide from bouncing open. Because the mechanism requires a spring force to pull the load closed, it will also affect the opening force.
But, it is not locked in this position. To overcome the hold you need to provide an additional force to the slide, by pushing firmly, and it will overcome the feature and move inward.
This is a useful feature for slides used on keyboard shelves, for example.
A lock out feature on a slide will be a physical lever or latch that has to be operated before the slide will move. For example, the 9308 has a lever at the front end and the 0305 has a push latch toward the centre of the slide mechanism.
Slides with lock-out are more usually used to support equipment that needs to be held fully open and static during maintenance, for example.
