Installation of oil-free bearings for self-lubricating bearings must be carried out in dry and clean environment. Before installation, the quality of the mating surface of the shaft and the shell, the end face of the shoulder, the groove and the connecting surface should be carefully checked. All mating connection surfaces must be carefully cleaned and deburred, and the unprocessed surface of castings must be cleaned of moulding sand.
Oil-free bearings should be cleaned with gasoline or kerosene before installation. Self-lubricating bearings should be used after drying, and good lubrication should be ensured. Oil-free bearings are generally lubricated with grease or oil. When grease lubrication is used, the grease with superior properties such as no impurities, anti-oxidation, anti-rust and extreme pressure should be selected. Self-lubricating bearings, grease filling of oil-free bearings and oil-free bearing box volume of 30% - 60%, should not be too much. Double-row tapered roller oil-free bearings with sealing structure and pump shaft oil-free bearings have been filled with grease, which can be directly used by users, and self-lubricating bearings can no longer be cleaned.
