The rolling contact components of HIWIN R50-20T4-FSI ball screws require good lubrication to reduce friction and wear. Regular lubrication with appropriate grease or oil is recommended, and the lubrication interval should be adjusted according to operating speed, ambient temperature, and load conditions. Lubrication frequency should be increased in dry or dusty environments.

The surface of the HIWIN R50-20T4-FSI screw should be kept clean to prevent dust, metal shavings, and other impurities from entering the nut, which could cause ball seizure or surface scratches. Wipe with a soft, lint-free cloth and use a dedicated cleaning agent.
