AbolishedPowder metallurgy plain bearing--Spherical type--Types， dimensions and tolerances
滑动轴承 粉末冶金球形轴承型式、尺寸与公差
Application Summary AI generated
This standard specifies the types, dimensions, and tolerances for spherical plain bearings manufactured using powder metallurgy. It is applied in mechanical systems where self-lubricating, wear-resistant spherical bearings are needed, such as in automotive suspension joints, agricultural machinery linkages, and industrial automation equipment. The standard ensures interchangeability and consistent fit for these bearings in low-speed, oscillating motion applications.
