Motion of a ball in a ball bearing

Wear, 1961
Abstract A magnetized ball rolling in a ball bearing induces an alternating current in a coil wound on the outer ring. The period of the current represents one revolution of the ball. Deviation from ideal motion of the ball occurs as slip and spin. The former is shown by the prolongation of the period.

Ball-Bearing Keratometry

American Journal of Ophthalmology, 1978
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.

The Correct “Ball Bearings” Data

Lifetime Data Analysis, 2002
The 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.

Routes To Chaos In Ball Bearings

Journal of Sound and Vibration, 1993
Abstract The dynamic motion of a lightly loaded ball bearing is studied in order to show and to gain an understanding of the different mechanisms involved in transitions to chaotic behaviours. By varying a control parameter, different routes to chaos are described.

Ball-Bearing Slides

Journal of Fluids Engineering, 1948
Abstract From personal experience the author gives examples of progress made in reducing friction in sliding movements to a minimum, with the addition of preloading of the slide mechanism, so that higher operating speeds, greater precision of product, and longer life at lower cost are possible.
