Composite Bearing Material CM1 -Guide PTFE Bushing
Tin-Plated Composite Bearing Material CM1 Guide PTFE Bushing is a
high-performance bearing component that combines the advantages of
tin plating, composite material, and PTFE (Polytetrafluoroethylene)
bushing. The tin plating provides excellent corrosion resistance
and enhances the surface hardness of the bearing, while the
composite material ensures strength and durability. The PTFE
bushing, known for its low friction and high wear resistance,
further improves the overall performance of the bearing. This
combination results in a bearing that is suitable for a wide range
of applications, especially those requiring high reliability and
long service life.
