Oilless bearing: SF - 1 is a combined metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, is based on steel substrate, sintering spherical bronze powder, rolling on the surface of modified ptfe. By load matrix, and the special formula of compound lubrication lubrication materials.It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion, bearing not only saving, energy saving, and its working life is longer than normal sliding bearing.Current products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line.
