High Cost Performance Oil Free Bushings Sliding bearing



It is made of steel plate as matrix, sintered spherical bronze powder in the middle, rolled PTFE and mixture on the surface.It has the characteristics of small friction coefficient, wear resistance, corrosion resistance and no need of lubricating oil. The utility model has the advantages of low cost, small volume, avoiding shaft biting, low noise, etc.The products have been widely used in the moving parts of various machines.

PTFE Coatings
Small friction coefficient,small resistance,protect the matched shaft
Copper Powder Layer
Good wear resistance and thermal conductivity,which can quickly diffuse the heat during operation
Low Carbon Steel Layer
Improve bearing capacity and heat transfer
Copper Plating Layer
Has good corrosion resistance
