Friction Rings

ROTAFRIX® friction rings are the result of many years’ experience in the field of drive technology. With their special elastomer materials, they offer optimal properties for high-performance rolling-contact drives with high transmission capacities.

ROTAFRIX® friction rings consist of a contact face, a base layer and a strength member.

Contact Face

The properties of the surface layer are matched to the special requirements imposed on it. A choice of two abrasion-resistant compounds is therefore available:


  • Natural rubber basis
  • Hardness 73 Shore A
  • Permissible ambient temperature -30 °C to +70 °C, from 30 °C with reduced contact force


  • Polychloroprene rubber basis
  • Hardness 83 Shore A
  • Permissible ambient temperature -30 °C to +90 °C, from 50 °C with reduced contact force
  • Largely resistant to many technical oils and greases

Base Layer

The base layer consists of a special hard elastomer material. It is firmly bonded to the contact face by means of vulcanization and contains the strength member. The base layer is manufactured for both cylindrical and tapered hub finishes.

Strength Member

The strength member consists of steel reinforcing wires. These keep the friction ring under constant tension and ensure a particularly firm fit on the hub.
Friction rings are sold without the hub.
