Self-lubricating bearing is a component specially used in industrial production equipment. The main advantage is that it has a small friction coefficient and is relatively wear-resistant. According to the different materials used to make self-lubricating bearings, they can be divided into solid-inlaid self-lubricating bearings, composite self-lubricating bearings, special materials self-lubricating bearings and bimetallic self-lubricating bearings. In addition, according to different working conditions and uses, Choose self-lubricating bearings made of different materials.
Self-lubricating bearings are particularly suitable for motion ranges in oil-free, high-temperature, high-load, low-speed, anti-fouling, anti-corrosion, and strong radiation environments, as well as special operating conditions where lubricating grease cannot be added at all when infiltrated in water or other solutions use.
So, what are the advantages of self-lubricating bearings?
1. Oil-free or less oil-lubricated bearings are suitable for places where it is impossible or difficult to refuel. It can be used without maintenance or less maintenance.
2. Good wear resistance, low friction coefficient and long service life.
3. There is a proper amount of elasticity and plasticity, 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 speeds, thereby ensuring the working accuracy of the machine.
5. The machine can reduce vibration, noise, pollution, and improve working conditions.
6. The transfer film can be formed during the operation, which can protect the grinding shaft without the phenomenon of shaft biting.
7. Low hardness requirements for grinding shafts, unconditioned shafts can be used, thereby reducing the difficulty of processing related parts.
8. Thin wall structure, light weight, can reduce the mechanical volume.
9. The bushing is made of brass, which can be used in corrosive media.
