Abstract：Aiming at the differences of the specifications and the loaded measuring methods for the radial clearance of miniature deep

groove ball bearings among the current standards，the theoretical calculations were presented and the increment of the radial clearance

was analyzed. By using the rolling bearing radial clearance loaded measuring method，the miniature deep groove ball bearing was deeply

analyzed. The results indicate that the theoretical results calculated by this method basically comply with the measured values.

Key words：miniature deep groove ball bearing；radial clearance；loaded instrument measuring method；measuring load；increment of

clearance
