Fatigue Tests of 150φ Whitemetal Bearings

Abstract

Whitemetal is a superior material in conformability, embeddability and compatibility. It is commonly used for ship's large bearings such as stern tube bearings, for it is easy to get the comparatively refined and uniform matrix when it is employed in large bearings. The thickness of whitemetal is employed usually 3 to 4 millimeters, but it is not certain how the thickness of whitemetals is estimated in terms of fatigue strength.
This paper we describes an experimental study of fatigue behavior of whitemetal bearings. The fatigue tests of tin-base and lead-base whitemetal bearings by giving alternating load have been performed and the metal damage ratings as to material, thickness and lining have been examined.
