Must the bearings be cleaned before installation?


About whether the imported bearings are cleaned before installation, there are many people still have doubts, some bearings installation users think that the bearing itself has a layer of lubricating oil, think that the installation does not need to clean, and some bearings installation users think that the bearings before installation or to clean.Because the bearing surface is coated with anti-rust oil, you must use clean gasoline or kerosene carefully cleaned, and then coated with clean high quality or high-speed high temperature grease before installation.


The influence of cleanliness on rolling bearing life and vibration noise is very great. However, we would like to remind you that fully enclosed bearings do not need to be cleaned.

Most of the newly bought bearings are covered with grease. These oils are mainly used to prevent the bearings from rusting and do not lubricate, so they must be cleaned thoroughly before installation.
