... of an oil seal is a function of the lubricant viscosity, lip angle, seal material, surface roughness, and rotational speed, and is therefore rather complex. However, from the prestudy presented by Baart et al. [( 9 )], it was found that pumping is not significant in the experimental setup used and does...
