Ball and Needle Bearing Friction Correlations Under Radial Load Conditions

Needle bearings are perceived to have lower friction than ball bearings for the same shaft diameter, although no experimental data were found to substantiate this claim. To obtain accurate bearing friction values for candidate bearings, a series of friction measurements under different radial load and lubricant conditions was made.

BABBITT METAL - WHAT IS IT AND WHAT DO WE USE IT FOR? - …

Babbitt metal also has properties that help it reduce friction which makes it a good material for use in a plain bearing.Babbitt metal is soft and can be easily damaged if not treated correctly. This would make it seem unsuitable for use as a bearing surface, however, the structure of the alloy is made up of small, hard crystals which are dispersed in a matrix of softer alloy.
