What determines the service life of graphite bearings?

1. The service life of graphite bearings, the service life of rolling graphite bearings is the number of revolutions (or the number of hours working at a certain speed). Definition: The graphite bearing in this life shall have initial fatigue damage (flaking or defect) on any graphite bearing ring or rolling body. But in laboratory experiments or theoretical applications, it can be clearly seen that the theoretical life of the same graphite bearings is different under the same working conditions.

In addition, there are several different definitions of graphite bearing life, one of which is the so-called working life, that is, the theoretical life that graphite bearings can reach before they are damaged is caused by wear, usually not by fatigue, but by wear, corrosion and seal damage.

2.Adhere to clean graphite bearings and their surrounding environment. Even if invisible dust enters graphite bearings, it will increase the wear, vibration and noise of graphite bearings.

These special operating conditions are when the rolling surface (track and rolling parts) is effectively separated by a smooth oil film and the possible appearance damage caused by contaminants is limited. In fact, under ideal conditions, the so-called durable graphite bearing life is possible.

3.Be careful when using the device. Heavy punches are not allowed. Hammer is used to hit the graphite bearing directly and the pressure is transferred through the roller.
