Metal free lightweight linear guides reducing cost and weight

Treotham presents the expanded drylin W modular system
from motion plastics specialist igus, featuring linear guides with rails made
of glass-fibre reinforced plastic (GRP). This new metal-free alternative is
finding application in diverse environments from vehicle construction to
laboratory technology, helping users reduce cost and weight in their overall

Glass-fibre reinforced plastic, or GRP not only offers
a lighter solution compared to metallic alternatives but also provides very
high media resistance as well as non-magnetic properties. While expanding their
extensive drylin W modular system for linear technology, igus developed a GRP
rail on which a plastic carriage is used.

According to Stefan Niermann, head of the drylin
linear and drive technology division at igus, the drylin W profile made of
glass fibre is 20 percent lighter than aluminium, 70 percent lighter than steel
and also 50 percent cheaper than carbon. All these advantages contribute to
making igus’ GRP linear guide system a suitable alternative for applications
involving vehicle and aircraft construction as well as medical devices and measuring

The GRP and plastic combination is also suitable for industries
where highly dynamic movements play a role such as robotics, where users are increasingly
using the weight advantages of GRP components. Thanks to GRP’s excellent media
resistance, the new linear guide can also be used in an environment with
aggressive cleaning agents.

Similar to all igus products, the linear guides manage
completely without external lubrication and are impervious to dust and dirt. igus
also offers a high profile GRP rail option for greater stability, which allows
it to be mounted using clamping claws.
