POM composite thrust washerSKF POM composite thrust washers are suitable for rotating and oscillating movements, and can accommodate heavy axial loads. They have as standard a hole to take a pin or screw to prevent the washers from rotating on their seat. After an initial grease fill, they are optimized for minimal maintenance under tough operating conditions. Pockets in the sliding surface serve as grease reservoirs. Relubrication can extend bearing service life considerably.
- Cost-effective with long service life
- Very good frictional properties
- High load carrying capacity
- High sliding velocity
