Cleaning Bearings beforeinstallation

It is necessary to clean the bearing before the bearing is installed. Many installers may think that the bearing itself is new and unsealed, so they install it directly on the machine.This is actually a misunderstanding, we thought that is not opened in the bearing lubricating oil, so is installed directly, before installing are too lazy to clean bearing, need like everyone here is correct, not opened on the bearing in the oil, not oil, not for bearing operation, but in order to prolong the time to save the bearing, its protective effect, so, before installation must clean up the bearings, bearing surface coated with anti-rust oil, must use clean petrol or kerosene cleaning carefully, then coated with clean, high quality or high speed high temperature lubricating grease before installation.The influence of cleanliness on bearing life and vibration noise is very great.However, we would like to remind you that fully enclosed bearings do not require cleaning or refueling.
