The difference between c3 and c3 in insulated bearings

When we choose insulated bearing, we often encounter bearings with C3, what are the characteristics of bearing C3

C3 is the clearance of the bearing, that is, his axial clearance and radial clearance
Without C3 is the standard clearance.
The clearance of C3 is larger than the standard clearance

The bearing clearance refers to the amount of movement of the bearing when it is not attached to the shaft or the bearing housing, and the one of the inner ring or the outer ring is fixed, and then the unfixed one moves in the radial or axial direction. According to the direction of movement, it can be divided into radial clearance and axial clearance.
The size of the running clearance (called the working clearance) affects the rolling fatigue life, temperature rise, noise, vibration and other properties of the bearing.
When measuring the clearance of the bearing, in order to obtain a stable measurement value, a specified measurement load is generally applied to the bearing.
Therefore, when choosing an insulated bearing, it is necessary to know how much clearance the product needs. If you are not sure, please consult us.
