Hybrid linear bearing
October 1st 2009 Linear technology expert, igus, has
developed a new hybrid linear bearing
that both rolls and slides. Called
DryLin WJRM, the bearing system
reduces driving force significantly and
is said to be particularly suited to
applications that combine sliding and
rolling movements, such as manually
adjustable doors, guards, partitions
and locks, as well as light handling
tasks.
The lubricant-free plastic sliding
plain bearings ensure the hybrid linear
system is robust, insensitive to dirt and
humidity, as well as being lightweight
and cost competitive. The polymer
rollers, which are also maintenancefree,
allow easy manual adjustment of
heavy machine doors and protective
doors weighing up to 50kg. At a
defined installation position, the roller
bearing, which carries the main load,
reduces the overall driving force by a
factor of between four and five – this
eases manual operation considerably. More articles from igus (UK) Limited: |
