Installation of oil-free bearings for self-lubricating bearings must be carried out in dry, clean ambient conditions. The mating surface of the shaft and the outer casing, the end faces of the shoulders, the grooves and the joining surface must be carefully inspected before installation. All mating joint surfaces must be carefully cleaned and burred removed. The unformed surface of the casting must be cleaned of sand.

Oil-free bearings should be cleaned with gasoline or kerosene before installation. Self-lubricating bearings should be used after drying and ensure good lubrication. Oil-free bearings are generally grease-lubricated or oil-lubricated. When using grease lubrication, greases with superior properties such as no impurities, anti-oxidation, rust, and extreme pressure should be used. For self-lubricating bearings, the grease filling amount is 30%-60% of the volume of oil-free bearings and oil-free bearing housings, and should not be excessive. The double-row tapered roller oil-free bearing with sealing structure and the oil-impregnated shaft of the pump shaft are filled with grease, which can be used directly by the user. The self-lubricating bearing can no longer be cleaned.
