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.
These PTFE linings offer exceptionally low friction.
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.
The CSB-80 (PEEK+PTFE) gives this material excellent temperature
and chemical resistance combined with good load capacity and
is particularly suited for operation under arduous conditions
with oil lubrication.
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.
These materials can be formed into cylindrical and flanged
wrapped bushes, half-bearings, or a large variety of special
forms.
