Update Time:2018-08-22

A: Bearing surface coated with anti-rust oil,you must clean carefully with clean gasoline or kerosene, and then coated withclean quality or high speed high temperature grease before installation.Cleanliness is very important to bearing life and vibration noise. However, wewould like to remind you that fully enclosed bearings do not need to be cleanedand refilled.
