On the Miniature Ball Bearing

open access: yesJournal of the Japan Society of Precision Engineering, 1958
Experimental results on the lapping of steel balls with the diameter of about 1 mm are as follows:1. The rate of cutting in lapping steel balls is not proportional to the lapping pressure, owing to the crush of abrasives and the metallic contacts between the ball and the lap.

Discrete Dynamics of Balls in Cageless Ball Bearings

open access: yesSymmetry, 2022
Cageless ball bearings are often preferred as a back-up bearing for active magnetic bearings to support a falling rotor, but the contact between the balls of the cageless ball bearing may lead to the deterioration of the bearing performance and affect the dynamic stability of the rotor system.
