Bronze Solid Lubricating Bearings are precision-engineered from high-density casting bronze (CuSn6Zn6Pb3) embedded with graphite, providing exceptional wear resistance and smooth operation in high-temperature, medium-speed, and low-load environments. The integrated solid lubricant ensures reliable performance even when conventional oil lubrication is limited, extending service life and reducing maintenance.
High-Density Bronze Construction: CuSn6Zn6Pb3 alloy provides superior strength and durability compared with standard high-strength brass.
Embedded Graphite Lubricant: Delivers self-lubricating performance, reducing friction and protecting mating surfaces.
Excellent Wear Resistance: Optimized for high-temperature and low-load operating conditions.
Maintenance-Friendly: Suitable for applications where regular oil lubrication is impractical.
