Miniature deep groove ball bearings radial clearance on load measurement method

Current miniature deep groove ball bearings radial clearance in the standard specifications with on-load measurement problem difficult to achieve unity between the standard docking, mechanics method of calculation is given, for measuring the radial internal clearance of the bearing load increases were analyzed using rolling bearing radial load measurement, further analysis of miniature ball bearings. Research results show that the theoretical results obtained agree with the actual measurement results.
