igus® drylin® NT telescopic rails are, and always will, remain lubrication-free

Lubrication-free extendable rails in infinitely variable stroke lengths from 100mm to 600mm – maximum extended length: 2,000mm. The telescopic system consists of anodised aluminium guide rails and a sliding block of tried-and-tested high-performance iglidur polymer. This permits the best possible dry operation of telescopic rails.  One further benefit: in addition to being maintenance-free, these parts can be unconditionally used in hygienic environments.

No oil or grease can be transferred to other products, clothing or persons. Even applications in cleanroom sluices have already been implemented. But dry operation provides advantages even in dirty applications: dirt particles do not get stuck in the guide and are not compacted into a sticky mass.

Six reasons in favour of igus® telescopic rails

Robust telescopic rails by igus®

drylin® telescopic rails can cope with high temperatures, strong vibrations and more

Dirt-resistant telescopic rails by igus

Resistant to dirt
drylin linear guides can be deployed even in applications involving sand, swarf and dust

Corrosion-free telescopic rails by igus

Corrosion-free and media-resistant for use under water

Quiet telescopic rails by igus - particularly low-noise

Around four times quieter than equivalent linear bearings made of metal

Particularly light telescopic rails by igus

Up to 75% lighter thanks to high-performance polymers

FDA-compliant telescopic rails by igus

All systems operate without additional lubrication and are thus very clean

Longer product life cycle


drylin® linear technology uses  not a single drop of lubricating oil . In addition, our tribologically optimised materials produce less microabrasion than commercially available plastics.  Longer service life also has a positive net effect on the environment.

No lubrication required
