Self-lubricating filament wound composite plain bearing CSB

Composite Self-lubricating Bearings

PTFE-based metal-polymer materials:
Our metal-backed, PTFE-based (polytetrafluoroethylene) polymer bearing materials have a common structure, consisting of a steel backing bonded to a porous bronze sinter layer. This bronze sinter layer is impregnated and overlaid with the filled PTFE bearing lining.
The steel backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.

Thermoplastic-based metal-polymer materials:
CSB-20, CSB-22, CSB80 have a similar structure to the PTFE-based materials described above; but with these products, the bearing lining consists of a filled thermoplastic extruded tape.
These materials are generally designed to operate with marginal lubrication.CSB-20/22/80 are most commonly provided with a uniform pattern of indents in the bearing surface that act as grease reservoirs.
The CSB-22 (PVDF+POM) has lower friction and excellent wear resistance and high temperature bear compare with CSB-20.

2-layer materials:
The CSB-15/12/32 products consists of aluminum/steel/stainless steel as backed material and overlay the PTFE supply lower friction and lower weight, suitable for sports equipment OA machines and automotive industry.
The FR,CSB-3S products consists of bronze or stainless steel alloy mesh and have a special polymer bearing lining containing solid lubricants and fillers bonded to it. The metal mesh supply mechanical strength and support for the bearing lining. This construction allows extremely thin wall bearings and easy to installation.
