The installation of Self lubricating bearing must be carried out in a dry and clean environment. Before installation, the machining quality of the mating surface of shaft and shell, the end face of shoulder, groove and connecting surface should be carefully checked. All mating surfaces must be carefully cleaned and deburred, and molded sand must be removed from the unfinished surface of the castings.
Self lubricating bearing should be cleaned with gasoline or kerosene before installation, used after drying, and to ensure good lubrication, oil-free bearings generally use grease lubrication, but also oil lubrication. When grease is used, grease with excellent properties such as impurities, oxidation resistance, rust prevention and extreme pressure should be selected. The grease filling volume is 30%-60% of oil free bearing and Self lubricating bearing box, not too much. Double row tapered roller Self lubricating bearing with sealing structure and pump shaft oil-free bearings have been filled with grease. Users can use them directly and can not clean them again.
