Bearing data

Dimension standardsISO 7063 and ANSI/ABMA Standard 18.1 (where standardized)

Profile of the outer ring running surface

  • KR .. (B) designs
    Radius = 500 mm
  • Other designs
    Improved crowned profile for better load distribution, higher stiffness and reduced wear
Tolerances

For additional information → Tolerances

Normal, except:

  • KR, KRE, KRV designs: ISO 7063
  • diameter of the crowned running surface: 0/–0,05 mm
  • stud shank diameter: h7
  • eccentric collar diameter: h9

Values for Normal tolerance class: ISO 492 (table 1)

Values for ISO tolerance classes: h7 and h9 (table 2)

Internal clearanceBetween C2 and Normal
Values: ISO 5753-1 (table 3)
Values are valid for unmounted bearings under zero measuring load.
