1)       C2 is only suitable for P6 or higher;
2)       The deviation of measuring load is 10%;
3)       This table isn’t suitable for 6200 and 6300;
4)       The difference in clearance between the maximum and minimum of the same bearing should conform to the stipulation of Table5.

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.

0-53-8C2

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.

5-106-12C0

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.
