ISO 3245:2015规定了无内圈拉制杯形滚针轴承的外形尺寸和首选尺寸,以及最小倒角尺寸限制。还规定了带有一个封闭端的轴承的封闭端厚度尺寸。
此外,还规定了滚针补孔直径的尺寸公差和拉制杯宽度的公差。
附录A中给出了轴滚道和壳体孔公差的信息值。
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.
