Oil-Impregnated Wear-Resistant Phenolic Bearings and Grown Cast Iron Bearings

Measurement of Wear in Radial Journal Bearings

In this article, the measurement of wear i n radial journal bearings is discussed, where a distinction is made between stationa y and non-stationa y contact conditions. Starting with Holm/ArchardS wear law, equations are derived for the calculation of the specific wear rate k of the bearing material as afunction of the wear depth d, measured after an experiment or a period of use i n practice. ...

Electrostatic wear monitoring of rolling element bearings

Research and development work at the University of Southampton using an electrostatic condition monitoring system developed by Smiths Aerospace Information Systems has shown that electrostatic charge signals can be used to detect the onset of wear in lubricated tribo-contacts. Preliminary investigations have already demonstrated the viability of this system when tested on a laboratory-based pin...

Wear Performance of Ceramic-On-Metal Hip Bearings

Ceramic-on-metal (CoM) bearings are considered to be a promising alternative to polyethylene-based bearings or hard-on-hard bearings (Ceramic-on-Ceramic (CoC) and Metal-on-Metal (MoM)). Although, CoM shows lower wear rates than MoM, in-vitro wear testing of CoM shows widely varying results. This may be related to limitations of wear-measuring methods. Therefore, the aim of this study was to imp...

Bearings: Technology and Needs

A brief status report on bearing technology and present and near-term future problems that warrant research support is presented. For rolling element bearings a material with improved fracture toughness, life data in the low A region, a comprehensive failure theory verified by life data and incorporated into dynamic analyses, and an improved corrosion resistant alloy are perceived as important ...
