What are the characteristics of bearing with C3

When we choose bearings, we often encounter bearings with C3. What are the characteristics of bearings with C3

C3 represents the clearance of the bearing, that is, its axial clearance and radial clearance

Anything without C3 is standard clearance.

C3 has a larger clearance than standard clearance

The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box and one side of the inner or outer ring is fixed, and then the side that is not fixed moves in radial or axial direction. According to the direction of movement, it can be divided into radial clearance and axial clearance.

The size of operating clearance (called working clearance) affects the rolling fatigue life, temperature rise, noise, vibration and other properties of bearings.

When measuring the clearance of a bearing, a specified measurement load is generally applied to the bearing in order to obtain a stable measurement value.
