Fault severity classification of ball bearing using SinGAN and deep convolutional neural network
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021Condition monitoring and diagnosis of a bearing are very important for any rotating machine as it governs the safety while the machine is in operating condition.

We obtained steel test balls for keratometer calibration at nominal cost by using a selected set of steel ball bearings, readily available for nonoptical purposes. The set of keratometer tests balls each have an accuracy of greater than one part in 1,000.

A Novel Test Rig for the Investigation of Ball Bearing Cage Friction
Tribology Transactions, 2021This article presents a novel experimental test rig for the investigation of friction between a ball and cage of a deep groove ball bearing (DGBB). The experimental apparatus was designed and developed to replicate the orientation and dynamics of a full ...

The bending of races of the flexible ball bearing in a harmonic reducer inevitably results in significant hoop stresses, which leads to the bearing working under a complex stress state. Studies show that hoop stresses can affect bearing life considerably,

The Correct “Ball Bearings” Data
Lifetime Data Analysis, 2002The famous data on fatigue failure times of ball bearings have been quoted incorrectly from Lieblein and Zelen's original paper. The correct data include censored values, as well as non-fatigue failures that must be handled appropriately. They could be described by a mixture of Weibull distributions, corresponding to different modes of failure.
