This book deals with the characterization and performance properties of rolling bearings. Bearing manufacturers are increasingly under pressure due to the tense economic situation and competitive markets. The main criteria for companies are consistently high quality at market-compliant prices, as well as shorter delivery times to secure their positioning in the global market. To gain further market share and build a competitive edge, this work describes the tribological system of rolling bearings and the associated manufacturing and production processes. The in-depth knowledge developed from this enables economical and productive manufacturing of specialized bearing sizes.
