Curved linear guide with radii that can be chosen individually

Based on the proven drylin® W series, igus® is offering curved linear guides that are customised and equipped with guide carriages specifically developed for use with rails of various radii. This results in innovative solutions for applications with limited installation space, e. g. in operator ergonomics, stage technology or in the driver's cab of commercial vehicles, where monitors and control systems are designed in such a way that safe and easy accessibility is guaranteed.
