Bearing data
Needle roller / angular contact ball bearings
Dimension standards | Boundary dimensions: ISO 15 – dimension series 59, except for following inner ring parameters in the NKIB 59 series:
|
Tolerances
For additional information → Tolerances | Normal, except for width of the complete inner ring in the
NKIB 59 series: 0/–0,3 mm
|
Internal clearance | Normal (bearings with an inner ring)
Check availability of C2, C3 or C4 clearance classes Values: ISO 5753-1 (table 2) Values are valid for unmounted bearings under zero measuring load. |
Permissible misalignment | Misalignment increases bearing noise and reduces bearing service life. |
Needle roller / thrust ball bearings
Dimension standards | Boundary dimensions: DIN 5429-1,
except for:

Values: |
|
Operating clearance | Bearings without an inner ring
Range slightly less than Normal if recommended tolerances (table 5) applied |
|
Permissible misalignment | Cannot tolerate any misalignment. |
