sliding bearing and bushing technology
1. No oil lubrication or less oil lubrication, suitable for places where it is impossible to add oil or it is difficult to add oil. It can be used without maintenance or with 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 a wider contact surface and improve the bearing capacity of the bearing.
4. The static and dynamic friction coefficients are similar, which can eliminate crawling at low speed, thereby ensuring the working accuracy of the machine.
5. It can make the machine reduce vibration, reduce noise, prevent pollution and improve working conditions.
6. The transfer film can be formed during the movement to protect the friction shaft without biting the shaft.
7. The hardness of the friction shaft is low, and more shafts without tempering treatment can be used, thereby reducing the difficulty of processing related parts.
8. Thin wall structure, light weight, can reduce mechanical volume.
9. A variety of metals can be electroplated on the back of the steel, which can be used in corrosive media; it has been widely used in sliding parts of various machines.
