The difference between self lubricating joint bearings and oil lubricated joint bearings
2, non self-lubricating bearings or oil lubricated bearings, made of ordinary bearing materials, the use of the provisions of the process should be filled with lubricating oil, otherwise, the bearings may be damaged by friction and wear.3 、 powder metallurgy bearing is a kind of self-lubricating bearing. Powder metallurgy material itself has a large number of pores, after the completion of production, in the oil immersion, that is, oil bearing, self lubrication characteristics.
Bearings can be divided into self-lubricating bearings and non self lubrication bearings (oil lubrication) two broad categories1. Self-lubricating bearings are made of materials with oil structure. Lubrication is not needed in use, and bearings can be replaced after a certain period of time.
4 、 non self lubrication bearings or oil lubricated bearings are made of bearing steel, and lubrication oil must be added in use.5, self-lubricating bearings are generally used in light and small load structure, and the use of bearings made of steel bearings, can withstand heavy load.
