SF-1 product description
SF-1 oil-free lubricating bearing is made of steel plate as base, sintered spherical bronze powder in the middle, and rolled PTFE and mixture on the surface. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. It can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting the shaft and reduce the noise.
