Machine Door: polymer rollers assist igus’
hybrid linear system
Hybrid roller bearing with tribo-polymer sliders halves coefficient
of friction in lateral position
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, igus offers a cost-
effective and visually appealing complete solution.
In the packaging industry, beverage industry, Pharmaceutical Industry &
Food Industry 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 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 Case Erector Machine doors, Food &
Pharma Machine Doors
