Most ball bearing telescopic slides are designed to be mounted in pairs vertically, on the sides of drawers or the moving unit.
There are some slides that can be mounted flat beneath the moving unit.
If slides are mounted horizontally (flat mount) the load rating is decreased to approximately 25% of the vertical load rating. Some slides may have a lower or higher percentage.
Look at the individual product datasheets or in the e-catalogue for this symbol:
Linear slides such as the 1312 and 0115RS perform better when flat mounted because the moving member is fully supported on ball bearings at all times.
The DA0115RC uses re-circulating ball carriages and is ideally suited for this orientation of mounting; see the datasheet for details of load ratings.
Mounting slides in different configurations will affect performance and load rating and we always recommend that you test the slide in the intended application.
Accuride has many years of experience in designing, testing and using telescopic slides. From this experience we have learnt that some slide profiles are just not suited to being used in the horizontal plane (flat mounted).
Problems can arise with deflection, especially with heavy loads on longer lengths, and with interference between the slide components, which can cause sliding components to grind together where clearances are minimal.
Some ranges have been designed, for example, with minimal wrap on the intermediate member (IMM), or the shape of the outer member (OM) has a flatter shape allowing lateral movement when flat mounted.
These cross sections have no problem handling loads in vertical/side applications, but when used flat, the members and ball retainer could easily disengage from the mating members, or grind / rub together.
