Bearing data

Dimension
standards
Boundary dimensions:
ISO 355 (single bearing)
Tolerances

For additional
information
Tolerances
  • Normal
  • tighter geometrical tolerances for bearings with designation suffix CL7C
  • check availability of P5

Values:
ISO 492 (table 1, table 2)

Total width tolerances:
not standardized (table 3)

Internal clearance
For additional
information
Internal clearance

Standard (table 4)

Other clearance values are identified by the designation suffix C followed by a three-digit number. For clearance values not listed in the product tables, contact SKF.

Values are valid for unmounted bearing sets under measuring loads of:

  • D ≤ 90 mm
    → 0,1 kN
  • 90 < D ≤ 240 mm
    → 0,3 kN
  • D > 240 mm
    → 0,5 kN
Misalignment

Where misalignment cannot be avoided, SKF recommends using a face-to-face arrangement.

Any misalignment increases bearing noise and reduces bearing service life.
