本标准用于修理机器或机械时供更换用的修理滚动轴承(其类型按照POCT520——55附录上所列).一、技术条件;1.根据基本尺寸精度和旋转精度修理轴承分为三种精度等极.1级精度;代号为HP.2极精度;代号为OP.3级精度;代号为YP.2.HP级轴承基本尺寸(不包括向心推力轴承的宽度),公差应符合于POCT—520—55中H级轴承的规定.OP和YP级轴承应符合于本标准的规定.向心推力轴承的装配高度公差应符合本标准之10和11表中的规定.
This standard is used to repair the machine or machine for replacement with the repair of rolling bearings (its type in accordance with POCT520--55 appendix listed.) First, the technical conditions; 1 according to the basic dimensional accuracy and accuracy of rotation Repair bearings are divided into three types of accuracy Grade precision; code-named HP.2 very precision; code-named OP.3-level accuracy; code-named YP.2.HP-class bearings basic dimensions (excluding the width of radial thrust bearings) tolerance should be consistent with the POCT -520-55 class H-class bearings.OP and YP-class bearings should be consistent with the provisions of this standard.Cartirectional thrust bearing assembly height tolerances should be consistent with the provisions of the standard 10 and 11 table.
