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.

Ball-bearing motors

IEE Proceedings A Science, Measurement and Technology, 1993
Two different ball-bearing motors have been investigated. The experimental results do not agree with the prevailing electromagnetic theories of ball-bearing motor operation. The results suggest that the driving force arises from an electromagnetic interaction between the ball race and the surface of the ball in the region of their contact point.

Misaligned ball bearings

Wear, 1970
Abstract Misalignment of rolling bearings is a form of abuse which can produce adverse conditions and shorten bearing life. The basic aspects and causes of misalignment are considered along with its effects and diagnosis. Guide lines are given to assist minimising the problems that occur.
