An Experimental Investigation of Cylindrical Roller Bearings Having Annular Rollers

Abstract

This study deals with an experimental investigation of a cylindrical roller bearing having annular rollers. Comparisons are made with a solid roller bearing having the same configuration and dimensions. Radial deformations and load distribution between rollers are measured under static load and compared with numerical solutions. Bearing temperature rise and roller wear are investigated in a specially designed tester. A radioactive tracing technique is utilized for the measurement of roller wear and proved to be reliable for wear detection. The results show several advantages of annular rollers over the solid rollers.
