PTFE composite thrust washerSKF PTFE 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. The material provides good heat dissipation, therefore enabling relatively high sliding velocities.
- Maintenance-free operation
- Cost-effective with long service life
- High operating temperatures
- High load carrying capacity
- High sliding velocity
