GB/T 4604.1-2012 in English

《GB/T 4604.1-2012滚动轴承 游隙 第1部分：向心轴承的径向游隙》由TC98（全国滚动轴承标准化技术委员会）归口，主管部门为中国机械工业联合会。

1 Scope

This Part of GB/T 4604 specifies values of radial internal clearance for the following types of radial rolling bearings:
— Radial contact groove ball bearings, except those for insert bearings,
— Double-row self-aligning ball bearings,
— Cylindrical roller bearings,
— Needle roller bearings, except drawn cup needle roller bearings,
— Toroidal roller bearings,
— Double-row self-aligning roller bearings.
This Part gives radial internal clearance values for all six types of bearing with cylindrical bore and also for double-row self-aligning ball bearings, cylindrical roller bearings, toroidal roller bearings and double-row self-aligning roller bearings with tapered bore.
Values of radial internal clearance for insert bearings are specified in ISO 9628.
