Self-lubricating polymer bearings

Paul Boughton

Igus bearings are available in variety of polymer materials, each with different properties. The company can custom design a bearing for almost any application.

Igus polymer materials are composed of a base polymer, fibres and filling material and a solid lubricant. The type of polymer material used determines the bearing’s properties; for example, its resistance to temperature extremes or chemicals as well as the life of the product.

These bearings are entirely lubricant-free. Where there is surface to surface contact, or any sliding motion, the solid lubricant is always present, making the polymer bearing entirely self-lubricating.

This tribological technology is used throughout the igus bearing range, including the iglidur plain bearings, xiros ball bearings, igubal spherical bearings, PRT slewing rings and DryLin linear systems.
