Product Specification
| High Light | CNC machining bronze bearing sleeve ，custom copper alloy CNC parts ，precision CNC machining services | ||
The bronze bearing sleeve is a sliding bearing component manufactured from high-density copper alloy through precision CNC machining, utilizing CuSn6.5P0.1 or CuSn8P0.3 bronze as base material. The product surface features regularly arranged diamond-shaped oil pockets that quickly form an oil film during initial operation, reducing friction coefficient. Suitable for medium-load and low-speed conditions, it offers excellent wear resistance and long service life, widely applied in various mechanical sliding parts.

We provide comprehensive customization services, offering precision machining based on customer drawings or samples. Non-standard size customization is supported with tolerance ranges up to housing hole H7, bearing f7 or h8 grades. Custom surface oil pattern designs (diamond or hemispherical), lubrication methods (grease or solid self-lubrication) and special structural forms (straight sleeves, flanged bushings, thrust washers, etc.) are available. Material formulations can be adjusted according to special working conditions to meet corrosion resistance, high temperature and other specific requirements.
