This paper presents effective ways to increase the carrying and reliability of thrust bearings. Technical solutions implemented by TRIZ Ltd have been considered. In comparative characteristics of the bearing took into account such factors as: capacity, peripheral speed at the average radius, speed at the periphery, specific pressure, specific lubricant consumption. Comprehensive analysis of the working conditions of bearing was aimed to protect against electroerosion.
