Does steel casting need lubrication after being used for a long time?

Steel castings require lubrication after prolonged use. Regular lubrication is necessary for steel castings that require movement, such as bearings, gears, etc. Lubrication can reduce wear, ensure the normal operation of components, and extend their service life. Applying some lubricant during the installation of steel castings can also help reduce wear. Therefore, in order to ensure the normal operation of steel castings and extend their service life, regular lubrication is necessary.
