Oil-free bearing bush

Self-lubricating and maintenance-free: Graphite automatically seeps out during friction to form a lubricating film, eliminating the need for additional oiling. Suitable for a wide operating temperature range of -40°C to +300°C.

Resistant to extreme environments: The brass matrix offers corrosion resistance and impact toughness, withstanding dynamic loads up to 100 N/mm². Ideal for harsh conditions such as dusty environments and seawater exposure.

With technological innovation at its core, we have dedicated ourselves to the field of oil-free bearings. Through independently developed core technologies, we have overcome industry bottlenecks, significantly extended product lifespans, and conquered multiple technical challenges, establishing new performance benchmarks for the sector. Leveraging our in-house copper foundry and CNC high-precision end-to-end machining system, we achieve vertical integration from raw material development to finished product delivery.

This breaks traditional supply chain barriers, ensuring quality control throughout the entire process. For bespoke requirements, we offer scientifically tailored raw material formulations and dedicated machining solutions, precisely matching each unique specification. Leveraging mature production controls, accumulated core technologies, and vertical supply chain advantages, our product qualification rate consistently ranks among the industry's highest. Short delivery cycles ensure efficient project progression, while our high cost-effectiveness ensures that advanced technology and customised services need not come at exorbitant cost. We forge your core competitiveness, blending performance, efficiency, and value.

Youyi Bearing will continue to attract talent, improve management systems, and strive to build a first-class brand. At the same time, it is increasing investment in the research and development of sliding bearings and component assemblies, aiming to deliver higher-quality bearings with superior performance.
