How much is the temperature of 6206 high temperature bearing
The temperature resistance value of high temperature bearings is not fixed to a value, and is generally related to the material used in the bearing. Generally, the temperature level can be divided into 200 degrees, 300 degrees, 40 degrees, 500 degrees, and 600 degrees. The commonly used temperatu...Read more -
How to do when bearing has vibration damage
Generation of vibration in bearings Generally speaking, rolling bearings themselves do not generate noise. The “bearing noise” that is usually felt is actually the sound effect of the bearing directly or indirectly vibrating with the surrounding structure. This is why many times the noise problem...Read more -

Bearing fit and clearance
It is very important to match the bearing inner diameter with the shaft and outer diameter with the housing when the bearing is installed. If the fit is too loose, the mating surface will produce relative sliding, which is called creep. Once creep occurs, it will wear out the mating surface, dama...Read more -
What is clearance and how is clearance measured for rolling bearings?
The clearance of a rolling bearing is the maximum amount of activity that holds one ring in place and the other in radial or axial direction. The maximum activity along the radial direction is called radial clearance, and the maximum activity along the axial direction is called axial clearance. G...Read more -
