Study on Life Distribution for Ball Bush

Abstract

This paper introduce the result of a fatigue life test date of Ball Bush which is a kind of linear bearing. Collected life data is arranged by log normal distribution, 2-parameter, and 3-parameter Weibull distribution. Fluid polishing is carried out for the outer sleeve raceway of Ball Bushe, and the life test result is compared with conventional Ball Bush which is not carried out fluid polishing.
