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.
