650S3 Solid embedded self-lubricating bearings-Products

650S3 Solid embedded self-lubricating bearings

Copper alloy embedded solid lubricant self-lubricating bearings combine the wear resistance of copper alloys with the self-lubricating properties of solid lubricants, making them maintenance free during use. The product is widely used in high load, intermittent or swinging motion, such as automobile and locomotive production lines, water turbines, reservoir work/accident doors, plastic machinery, punch peripheral equipment, etc. According to the operating conditions, various types of copper alloys can be provided.
