|d, D: ISO 15
D ≤ 47 mm → diameter series 0
D ≥ 55 mm → diameter series 9
Values: ISO 492 (table 2)
|Operating clearance||Bearings without an inner ring
Range of C2 to C3 if recommended tolerances (table 3) applied
|Internal clearance||Normal (bearings with an inner ring)
Check availability of C2, C3 or C4 clearance classes
Values: ISO 5753-1 (table 4)
Values are valid for unmounted bearings under zero measuring load.
|Permissible misalignment||≤ 3° static misalignment
No dynamic misalignment
Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values these effects become particularly noticeable.
