|Boundary dimensions: ISO 1206:2001 for bearings in the (R)NA 48, (R)NA 49 and (R)NA 69 series
P6 or P5 on request
Values: ISO 492:2014 (table 2, table 3, table 4)
Bearings without an inner ringSuitable ranges (table 5) if:
|Internal clearance||Normal (bearings with an inner ring)
Check availability of C2, C3 or C4 clearance classes
Values: ISO 5753-1:2009 (table 6)
Values are valid for unmounted bearings under zero measuring load.
|Misalignment||≈ 1 minute of arc
The permissible angular misalignment between the shaft and the housing depends on the size and internal design of the bearing, the radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only an approximate value is listed here. Any misalignment increases bearing noise and reduces bearing service life.
