SF-1X Oil Free Steel Bearing SS304 Sintered Spherical Self Lubricating
Sf-1x oil-free bearings are plain bearings made of steel plate, sintered spherical bronze powder, rolled with a mixture of PTFE and lead on the surface. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and no oil lubrication. Using this product can reduce the cost, reduce the size of the machine, avoid the phenomenon of shaft biting and reduce the mechanical noise and other advantages.
Products have been widely used in various machinery sliding parts, such as printing press, lift, textile machine, tobacco machine, fitness machine, hydraulic truck, micro-motor, solenoid valve, automobile, motorcycle and agricultural and forestry machinery, etc.
