Inch R Series Bearing
Inch R Series Bearing is an important component in contemporary machinery. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
When dismantling the Inch R Series Bearing for inspection, first record the appearance by means of photography. Also, confirm the amount of lubricant remaining and sample the lubricant before cleaning the Inch R Series Bearing. Its cleaning is divided into rough washing and fine washing, and a metal mesh frame can be placed at the bottom of the container used. For rough washing, remove grease or build-up with a brush, etc. in oil. If the Inch R Series Bearing is rotated in oil at this time, be careful that the rolling surface may be damaged by foreign matter or the like. For fine washes, turn the Inch R Series Bearing in oil slowly and carefully. The commonly used cleaning agent is neutral non-water diesel oil or kerosene, and sometimes warm lye is also used as needed. Whatever cleaning agent is used, it should be filtered frequently to keep it clean. Apply anti-rust oil or grease to Inch R Series Bearing immediately after cleaning.
