Characteristics of oil free bearing series
1. No oil lubrication or less oil lubrication, suitable for places where oil can not be added or it is very difficult to add oil. It can be used without maintenance or less maintenance.
2. Good wear resistance, small friction coefficient and long service life.
3. It can distribute the stress on a wide contact surface and improve the bearing capacity.
4. The static and dynamic friction coefficients are similar, which can eliminate the creeping at low speed and ensure the working accuracy of the machine.
5. It can reduce vibration, noise, pollution and improve working conditions.
6. In the process of operation, it can form a transfer film, which plays a role in protecting the grinding shaft and has no shaft biting phenomenon.
7. The hardness of the grinding shaft is low, and the shaft without quenching and tempering treatment can be used, thus reducing the machining difficulty of related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
