Bearing data

Single direction bearingsDouble direction bearingsCartridge units
Boundary dimensionsISO 15:2011, only for BSA 2 and BSA 3 series that are in accordance with 02 and 03 ISO dimension series respectively

BSD series bearings partly follow ISO dimension series

P4 dimensional accuracy
P2 running accuracy
Values: ISO 492:2014 (table 1)

The values apply to individual bearings. For matched bearing sets, the axial run-out is usually within 2,5 μm if the bearing seats are machined precisely and the bearings are mounted properly.
