Description

Product description

SF-1 oil-free lubrication bearing is the rolled sliding bearing based on the matrix of steel plate, with the porous bronze powder sintered in the middle while the mixture of PTFE and lead rolled in the surface. It is with small friction coefficient, wear resistance, good corrosion resistance and oil-free lubrication. The application of such product can reduce the cost, reduce the mechanical volume, avoid the shaft engagement, and lower the noise.
