PTFE polyamide straight bushingSKF PTFE polyamide straight (cylindrical) bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads. They provide a cost-effective, self-lubricating solution, and are designed for dry sliding operations. Despite their thin-walled design, they are wear-resistant and can accommodate moderate loads. Their compact design provides good heat dissipation, therefore enabling relatively high sliding velocities.
- Maintenance-free operation
- Cost-effective
- Excellent corrosion resistance
- Electrically insulating
