The difference between the bearing with C3 and without C3

C3 is the bearing clearance, that is, his axial gap and radial clearance

C3 is the standard without clearance.

C3 clearance than the standard clearance is much larger

The so-called bearing clearance, referring to the bearing shaft or the bearing is not installed in the box when one of the inner or outer ring fixed, and then they are not fixed and either the radial or axial movement amount of movement. According to the direction of movement can be divided into radial clearance and axial clearance.

When operating with a clearance (clearance work called) the size of the rolling bearing fatigue life, temperature, noise, vibration and other performance impact.

When measuring the bearing clearance, in order to obtain a stable measurement value, the general measurement requirements imposed on the bearing load.
