Matched bearings Double row bearings

Boundary dimensions: ISO 355 (single bearing) • metric bearings: not standardized
• inch bearings: cones and cups dimensions of many inch
bearings → AFBMA Standard 19 (ANSI B3 19)
ANSI/ABMA Standard 19 2 has replaced the above
standard, but does not include dimensions.

• Normal • dimensional tolerances (except for width T): Normal
• tighter geometrical tolerances for bearings with designation • geometrical tolerances: P5
sufix CL7C
• check availability of P5 Values: ISO 492 (table 5, page 41, table 7, page 43, and
table 9, page 45)
Values: ISO 492 (table 5, page 41, and table 7, page 43)

Total width tolerances: not standardized (table 5, page 678)

Standard (table 6, page 679) • bearings are ready-to-mount units with an axial internal
clearance adapted for the actual application
Other clearance values are identiied by the designation sufix C • bearing components should be arranged in the prescribed
followed by a three-digit number For clearance values not listed order and may not be interchanged with components of
in the product tables, contact SKF another bearing
• designations with sufix C followed by a three- or four-digit 8
Values are valid for unmounted bearing sets under measuring number expresses mean value of the axial internal clearance
loads of: in μm (for clearance values not listed in the product tables,
contact SKF)
• D ≤ 90 mm → 0,1 kN
• 90 < D ≤ 240 mm → 0,3 kN
• D > 240 mm → 0,5 kN
