igus polymer rollers assist Treotham’s hybrid linear system

In order to move doors, monitors or even panels, users
rely on lateral installation of the linear systems. To enable the linear guides
to absorb these lateral forces better, igus has now developed a new hybrid
linear system. Two hybrid bearings provide low-friction adjustment with polymer
rollers and tribo-polymer slide elements. Combined with an easily fit rail
adapted to the new roller bearings, Treotham offers a cost-effective and
visually appealing complete solution.

In the packaging industry, furniture technology or
even in machine tools, drylin linear guides can be found wherever movement is
required. On tribologically optimised liners, the linear carriages slide on the
rail, ensuring precise and long-lasting adjustment. If a low driving force is
required for manual adjustments, rollers are used in the bearing element.
Especially for a lateral installation, the position of the rollers for the
force absorption is crucial.

As a solution for such applications, igus has now
developed two new hybrid roller bearings, which offer smooth adjustment with
low drive forces and maximum support at the same time. The WJRM-41-10 has two offset polymer rollers with optimised alignment
for better force absorption and easier rolling. The hybrid roller bearing
WJRM-31-10 with single roller is, in turn, the matching, supporting bearing on
the opposite side.

By using the two roller bearings, the
user can minimise the coefficient of friction by half and increase the service
life of the application. In both bearings, in addition to the rollers, there
are sliding elements made of the low-friction tribo-polymer iglidur J. The
lubrication-free and maintenance-free material is characterised primarily by
its low coefficient of friction in dry operation. Both bearings can be positioned
at the desired bearing clearance. These are very cost-effective if the bearings
are produced in the zinc die-casting process.

Smooth adjustments with low-friction

Using a top plate, the two new roller bearings from
Treotham can be expanded to a linear carriage. To ensure that the bearings can
also be used on the appropriate guide, igus has developed a low-profile hybrid
roller rail. This has a special geometry optimised for the hybrid roller
bearing. The rail has a simple design without visible holes and is able to
attach from the back with sliding blocks. This makes the new rail in
combination with the hybrid roller bearing ideal for lateral installation; for
example, in kitchen and furniture construction as well as in machine tools or
in jig construction.
