PTFE composite straight bushing, inch size
SKF PTFE composite straight (cylindrical) bushings, inch sizes, 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
