SF-1 universal steel base non-lubricated self-lubricating bearing 1 is not oil-lubricated or less-oil-lubricated and can be used without maintenance or maintenance. 2 Good wear resistance, low friction coefficient and long service life. 3 With appropriate amount of elasticity, the stress can be distributed on a wide contact surface and the bearing bearing capacity can be improved. 4 Static friction coefficient is similar, so as to guarantee the working accuracy of the machine. 5 The machine can reduce vibration, reduce noise, prevent pollution, and improve working conditions. 6 The transfer film can be formed during operation to protect the grinding shaft. 7 The hardness requirement of the grinding shaft is low, which reduces the processing difficulty of the relevant parts. 8 Thin-walled structure, light weight, can reduce the mechanical volume. 9 The back of the steel can be plated with various metals and can be used in corrosive media; it has been widely used in sliding parts of various machines.
