 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.
