Piping and Valve Steam Bushings Stainless Steel Bearings With Low
Friction
1. Product Description
Piping and Valve Steam Bushings Stainless Steel Bearings With Low
Friction are based on stainless steel substrate, the surface adhesion of
ptfe ethylene fiber and copper powder, after rolling processing
into a collar or stamping processing into a variety of forms such
as gasket. The product has the characteristics of high precision,
high load bearing pressure and excellent low speed and heavy
friction performance.Suitable for rotary and oscillating movement,
lower maintenance requirements due to the long re-lubrication
intervals.

3. Application
Piping and Valve Steam Bushings Stainless Steel Bearings With Low
Friction are widely applied in food machinery ,printing machinery ,electric
appliance etc.
4. Advantages
The product with oil fibre can protect the shaft, while machine in operation.It
is of low friction coefficient, good anti-wear,good
anti-corrosion,good running in property. It fits well in motion of circumgyration, swaying and to-and-fro.It can be used in food machine, pharmaceutical etc, due to
lead-free. It is mainly used in the condition of strong acid and
alkali,especially fit for the chemical Industry, pumps, valves etc.
