PTFE composite straight bushing

SKF PTFE composite straight (cylindrical) bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads.

Despite their thin-walled design, they can accommodate heavy loads. They also provide 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 and small operating clearance
