Self-lubricating bearings must be installed in dry, clean environment. Care should be taken to inspect the mating surfaces of the shaft and housing, the end face of the shoulder, the quality of the grooves and the connection surface. All mating surfaces must be carefully cleaned and removed from the burrs, and the cast surfaces must be cleaned in addition to the net.
Self-lubricating bearings should be installed with gasoline or kerosene before cleaning, dry use, and to ensure good lubrication, oil-free bearings are generally greased, can also be used oil lubrication. When using grease lubrication, should use no impurities, anti-oxidation, rust, extreme pressure and other superior performance grease. Grease filling capacity for oil-free bearings and oil-free bearing box volume of 30% -60%, should not be too much.
