The transported material must have a rigid riding surface that is supported by a minimum of three of the rollers. They are ideal for accumulation applications, and the rollers can reduce the inertia of products at a higher speed, making them useful conveyors after high speed sorting machinery.

Purpose-built linear bearings are available for frequently encountered tasks, such as pull-out equipment drawers or storable work surfaces. These usually light-duty devices let polymer wheels or ball bearings ride on stamped or rolled steel rails. Telescoping arrangements allow designing pull-out equipment drawers into cantilevered positions while supporting up to 50 lb or more for maintenance.
