TABLE4 SELECTION OF BEARING CLEARANCE
|
Operating Condition |
Clearance |
|
Clearance fit for inner and outer ring. Low axial load. No axial carrying requirement. Lower vibration and noise. Low speeds. |
0-5，3-8，C2 |
|
Lower frictional torque. Standard axial load. Average axial load carrying requirements. Slight interference fit for inner ring. Clearance fir for outer ring. Average/low speeds. |
5-10，6-12，C0 |
|
Extremely low frictional torque. High axial load. High axial load carrying requirements. Heavy interference fit to support high loads or shock loads. Large temperature gradient from inner ring to outer ring. High degree of shaft deflection. |
