GB/T 9161-2001 in English

《GB/T 9161-2001关节轴承 杆端关节轴承》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。
本标准规定了E、EH、G、GH和K系列杆端关节轴承的外形尺寸、公差、径向游隙和技术要求。杆端关节轴承的结构设计不必完全符合本标准的图示结构，但尺寸、公差和径向游隙应与本标准的规定一致。本标准适用于不同滑动材料组合的杆端关节轴承，供制造厂生产、检验和用户验收。本标准不适用飞机机架用杆端关节轴承和直接于液压缸上的专用杆端关节轴承。

1 Scope

This Standard specifies boundary dimensions, tolerances, radial internal clearances and specifications for dimension series E, EH, G, GH and K of spherical plain bearing rod ends.
Spherical plain bearing rod ends don’t need to conform to the designs illustrated but compliance is required as regards dimensions, tolerances and radial internal clearances specified.
The dimensions and tolerances specified in this Standard have been selected to permit the design and use of spherical plain bearing rod ends which incorporate radial spherical plain bearings having various sliding material combinations. .(for manufactures’ production, inspection and customers’ acceptance)
This Standard is not apply to the spherical plain bearing rod ends for airframe applications and specific spherical plain baring rod ends for direct connection to hydraulic cylinders.
