PCMF 252821.5 EPTFE composite flanged bushing

SKU: PCMF 252821.5 EPTFE composite flanged bushing

SKF PTFE composite flanged bushings are suitable for oscillating, rotating and linear movements, and can accommodate radial loads as well as axial loads in one direction. Despite their thin-walled design, they can accommodate heavy loads. They also provide good heat dissipation, therefore enabling relatively high sliding velocities.
