ROLLON Corporation's Telescopic Rail products are so different from existing drawer slides that the Company hesitates to refer to them as drawer slides.

The Telescopic Rail was designed to create a linear bearing that telescoped beyond its mounting structure. Our research and development team had to think outside the box to produce such a solution because this type of product did not exist.

Before ROLLON attacked the problem, drawer slides were simple, bent steel products suited for desk drawers, filing cabinets, keyboard trays and other light duty applications. In fields where high load capacities, reliability, low deflection, and smoothness of movement are important for a drawer slide-type extension, there was no solution. In most cases, engineers were forced to use homemade solutions or to double up on thicker gauge bent steel drawer slides. Drawer slides existed and linear bearings, of course, but drawer slides that could be used 24/7 with high loads and good precision had not been developed.

In creating the Telescopic Rail family, ROLLON's engineers succeeded in creating a telescopic linear bearing – similar in movement to a drawer slide but in function closer to a linear bearing.

Today, ROLLON's Telescopic Rail products are the industry leader because:

• They are made from cold-drawn bearing steel – never from bent sheet metal.
• They have hardened 60 HRc races to provide the smoothest movement at all times.
• They work well with shocks and vibrations that render other slides inoperative immediately.
• They have minimal deflection at the tip of the fully extended slide – even while carrying maximum loads.
• They can reach strokes of over 2 m (6.5 ft) in one direction and can double that by doing the same out the other side.

The Telescopic Rail family contains the following types of products:

• Telescopic slides with hardened races
• Telescopic slides with non-hardened races
• Semi-telescopic slides with rails that extend more than half of their length out of either side of the fixed part of the slide.
