The innovative, cost-effective hybrid linear bearing "DryLin WJRM" from igus GmbH, Cologne, combines rolling and sliding.
It was developed for the manual adjustment of machine and guard doors up to 50 kg.

The principle of the installation position for the new hybrid bearing: The main load is on the roller bearing (centre) which reduces the
driving momentum required. The plastic sliders compensate any lateral forces (right).
a further solution. For this purpose, the extremely compact system was modelled by the igus design engineers in such a way that the rollers fit inside without
increasing the design height, which remains at a low
18 mm. According to information from the manufacturer, the standard economic guide profiles can also be
used. These are available in three styles for shaft
diameter 10 mm: As individual rails for flexible guiding
distance and as double rails with a shaft distance of
40 mm or 80 mm for fast installation without timeconsuming alignment. The hybrid bearing housing is
made of blue-chromed diecast zinc.
