Values: ISO 492 (table 1, table 2, table 3)

The aluminium oxide layer on the external surfaces of either the inner or the outer ring does not affect accuracy.

Permissible axial displacement

smax → product table

NU design INSOCOAT bearings can accommodate axial displacement (fig. 1). Displacement of the shaft relative to the housing occurs within these bearings. As a result, there is virtually no increase in friction.
