PTFE polyamide flanged bushingSKF PTFE polyamide flanged bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads as well as axial loads in one direction. 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
