Unlike earlier lubrication studies using power law lubricants, where symmetric conditions were explicitly or implicitly assumed, this work presents a theoretical analysis of heavily loaded rigid asymmetrical rollers under combined rolling and sliding motions, by considering cavitation. The modified Reynolds' and energy equations under isothermal boundaries are obtained and solved simultaneously for many values of a sliding parameter U close to unity. It is seen that the presence of sliding enhances both pressure as well as temperature, and hence the consistency variation, as compared to the pure rolling.
