introduction： a. Oil bath lubrication Oil bath lubrication is the most common method of lubrication，Low fit、Lubrication of medium speed bearings，The bearing is partially immersed in the groove，The lubricating oil is carried by a rotating bearing part，The oil level of the tank should then flow back slightly below the center of the lowest rolling element。 b. Drip lubrication Drip lubrication is suitable for imported bearing parts that require a quantitative supply of lubricating oil，Drops of oil are generally per3-8One drop per second is appropriate，pass...
