Full Description

ISO 3245:2015 specifies the boundary dimensions and preferred dimensions to be used for drawn cup needle roller bearings without inner ring as well as the minimum chamfer dimension limits. Also specified are the closed end thickness dimensions for bearings with one closed end.

In addition, dimensional tolerances for the needle roller complement bore diameter and tolerances for the drawn cup width are specified.

Informative values for the tolerances for shaft raceway and housing bore are given in Annex A.
