What are sprockets with ball bearing
Chain-stretcher sprockets with ball bearing are supplied ready for mounting. They consist of a toothed wheel mounted on a ball bearing with double protection shield that guarantees high resistance against breakage and wear. The bearing requires no maintenance.
The wheels are made of C45 steel and toothed according to DIN 8187, ISO 606. The ball bearing can operate at a temperature from -20°C to +120°C.
