Material Structure and compositions:

5.Oil-free lubricating bearing series

1. No oil lubrication or less oil lubrication. It is suitable for places that cannot be refueled or difficult to refuel. It can be used without maintenance or less maintenance.

2. Good wear resistance, small friction coefficient and long service life.

3. There is an appropriate amount of elastoplasticity, which can distribute the stress on the wider contact surface and improve the bearing capacity of the bearing.

4. The static friction coefficient is similar, which can eliminate the creep at low speed, thus ensuring the working precision of the machine.

Key technical principle
The composite material used in the inlaid self-lubricating bearing is a new type of extreme pressure resistant solid lubricating material consisting of a metal substrate and a solid lubricant paste embedded in the hole or groove of the substrate. The metal substrate takes up most of the load during the rubbing process. After friction, the solid lubricant in the hole or the groove is transferred or reversely transferred to the friction surface, and a solid transfer film which is well lubricated, firmly adhered and uniformly covered is formed on the friction surface, and the friction and wear are greatly reduced. As the friction progresses, the embedded solid lubricant is continuously supplied to the friction surface, ensuring good lubrication of the friction pair during long-term operation.
