▊Material structure

DR22 sliding washers consist of three layers combining the excellent bearing properties of low-friction sliding layer with the high strength of a load carrying glass-fibre filled core layer.

The silding layer consists of an fluoroplastic filled with solid lubricants, designed to ensure good tribological properties and lower starting friction force.
