Self-lubricated bearings are made of high-strength brass, with centrifugal casting as the matrix, which play an important role in load-bearing. It is specially prepared graphite with good self-lubricated performance to achieve self-lubricated effect. The sintered hull produced by powder metallurgy is porous in nature. Its technical advantage is that it is easy to adjust the number, size, shape and distribution of pores in the manufacturing process. What are the differences between self-lubricating bearings and oil-bearing bearings? The following by Hangzhou self – lubricating bearing xiaobian to explain it.

Hangzhou self-lubricated bearing

1. Oil-bearing is a combination of metal powder, with 10-40% structural clearance. The built-in lubricating bearing matrix is made of centrifugal casting, with high matrix density and high fastening strength. Higher than oil bearing, longer service life than oil bearing.

2. The smooth raw material of the oil-immersed bearing is smooth oil, and the oil film is of satisfactory thickness, eliminating direct contact between two conflicting surfaces. At the moment, there is only one collision between the liquid molecules, so the coefficient of collision is very small (f = 0.001-0.008), which greatly reduces the impact and wear when the smooth material is embedded in the smooth bearing. It is a smooth, hard material even without oil. In this case, the excellent smoothing effect that can still be eliminated will ensure uninterrupted, continuous smoothness and smooth service life.

3. Bearing lubricating oil contains volatile oil, which is easy to be lost. Under high temperature and pressure, smooth oil film disappears and accelerates rapidly, which makes it impossible to obtain smooth effect in the shell. Graphite copper, in which solids collide in holes or grooves to form solids. The smoothing agent moves backwards or backwards to the conflicting surface, forming a rigid transport film with excellent flatness, firm adhesion and uniform coverage over the conflicting surface, thereby greatly reducing friction. Extreme conflict wear As the conflict progresses, the embedded smoothing agent is continuously transmitted to the surface of the conflict to ensure excellent smoothness in the long run.

These are the three major differences between self-lubricating bearings and oil-bearing bearings. Thank you for your understanding and support!
