information
Tolerances
  • rollers: ISO 3096 Grade 2 (grade G2)
    • tolerance of each gauge 2 μm
    • standard gauges (table 1)
    • specific gauge to be stated when ordering
  • U: ISO 3030 as far as standardized (‑0,2/‑0,8 mm)
Operating clearanceRange of C2 to Normal if:
  • fitted with standard gauge rollers (table 1)
  • recommended raceway tolerances (table 2) applied
  • normal operating conditions
Internal clearanceSpecific ranges: (table 3)

Permissible misalignment

≈ 1 minute of arc


Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline value these effects become particularly noticeable.
