Self lubricating bearing is a kind of component specially used in industrial production equipment. Its main advantages are small friction coefficient and wear resistance. According to the different materials of self-lubricating bearing, it can be divided into solid inlaid self-lubricating bearing, composite self-lubricating bearing, special material self-lubricating bearing and bimetal self-lubricating bearing. In addition, according to different working conditions and uses, self-lubricating bearing made of different materials can be selected.
The self-lubricating bearing is especially suitable for the motion range in the environment of no oil, high temperature, high load, low speed, anti pollution, anti-corrosion and strong radiation, as well as the special working conditions in which water or other solutions can not add lubricating grease.
So what are the advantages of self-lubricating bearings?
1. No oil lubricated bearings or less oil lubricated bearings are suitable for places where oil can not be added or it is difficult to add oil. They can be used without maintenance or with less maintenance.
2. Good wear resistance, low friction coefficient and long service life.
3. With proper elastic plasticity, the stress can be distributed on a wide contact surface, and the bearing capacity can be improved.
4. The static and dynamic friction coefficient is similar, which can eliminate the crawling at low speed, so as to ensure the working accuracy of the machine.
5. It can reduce the vibration and noise of machinery, prevent pollution and improve working conditions.
6. The transfer film can be formed in the process of operation to protect the grinding shaft without shaft biting.
7. The hardness requirement of grinding shaft is low, and the unconditioned shaft can be used, so as to reduce the processing difficulty of related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
9. The material of bushing is brass, which can be used in corrosive medium.
