Rolls and slides
November 1st 2009 Linear technology expert igus has
developed a new breed of hybrid
linear bearing that both rolls and
slides. Called DryLin WJRM, this
system reduces driving force and is
well-suited to applications that
combine sliding and rolling
movements, such as manually
adjustable doors, guards, partitions
and locks, as well as for 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 costcompetitive.
Maintenance-free polymer rollers
allow for easy manual adjustment of
heavy machine doors and protective
doors that can weigh up to 50kg. At a
defined installation position, the
roller bearing, which carries the main
load, reduces overall driving force by
a factor of between four and five. More articles from igus (UK) Limited: |
