China Oil-Free Bearing Bush Suppliers | Self-Lubricating Brass and Graphite Factory Products for Maintenance-Free Solutions
Product Features
★ Self-Lubricating & 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.

Frequently Asked Questions
Q What is a self-lubricating graphite bearing and how does it work?
A self-lubricating graphite bearing contains embedded graphite plugs within a brass or bronze matrix. During operation, friction causes graphite to seep onto the contact surface, forming a continuous dry lubricating film — eliminating the need for external oil or grease.
Q What temperature range are Youyi graphite bearings suitable for?
Youyi graphite bearings are designed for a wide operating temperature range of -40°C to +300°C, making them suitable for both extreme cold and high-heat industrial environments.
Q Can Youyi bearings be used in wet or corrosive environments?
Yes. The brass matrix provides strong corrosion resistance, making Youyi bearings well-suited for harsh conditions including dusty environments, outdoor exposure, and seawater contact.
Q Do you offer custom-specification bearing solutions?
Absolutely. We provide scientifically tailored raw material formulations and dedicated CNC machining solutions to precisely meet custom specifications, from dimensions to material composition and load requirements.
Q What is the maximum dynamic load capacity of these bearings?
Youyi graphite-embedded bearings can withstand dynamic loads of up to 100 N/mm², offering excellent performance under heavy and variable load conditions.
Q How does Youyi Bearing ensure product quality and fast delivery?
Youyi operates an in-house copper foundry combined with a CNC high-precision machining system, enabling full vertical supply chain control. This ensures end-to-end quality management, consistently high product qualification rates, and short, reliable delivery cycles.
