[0002] Sliding bearings are widely used in mechanical equipment to support rotating shafts and reduce frictional resistance. Traditional sliding bearings are typically made of metal materials such as cast iron, copper alloy, or steel, and rely on external lubricants such as oil or grease to reduce friction and wear.

[0003] However, the existing bearing seats need to be regularly filled with lubricating oil or grease during lubrication.
