Bearing data

Single row deep groove ball bearings

Dimension Boundary dimensions: ISO 15
standards Snap rings and grooves: ISO 464

Tolerances Normal
P6 or P5 on request

Except for:
SKF Explorer bearings
Dimensional tolerances to P6 and tighter width Geometrical tolerances:
tolerance: D ≤ 52 mm → P5
D ≤ 110 mm → 0/ –60 μm 52 mm < D ≤ 110 mm → P6
D > 110 mm → 0/ –100 μm D > 110 mm → Normal

information
† page 35 Values: ISO 492 (table 2, page 38, to table 4, page 40)

Internal clearance Single bearings
Normal
Check availability of C2, C3, C4, C5, reduced ranges of standard clearance classes or partitions of adjacent classes

Matched bearing pairs
Supplied either with clearance or preload:
• CA – small axial internal clearance
For additional • GA – light preload
information
† page 182 Values: ISO 5753-1 (table 6, page 252), except for stainless steel bearings with d < 10 mm (table 7, page 253)

Permissible ≈ 2 to 10 minutes of arc (single bearings)
misalignment
Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline values
these effects become particularly noticeable For matched bearing pairs, any misalignment increases bearing …
