Application of Ultrasonic Surface Wave for Rolling Bearing Flaw Detection

This paper analyzes the ultrasonic surface wave flaw detection technology for finished rolling bearing , and elaborates the probability of application of ultrasonic surface wave flaw detection . The results have shown that the bearing surface flaws can be detected effectively by ultrasonic surface wave without disassembly and the quality of finished bearings shall not be influenced. This detection reduces the difficulty in selective examination and countercheck of the bearings and provides credibility detection method for production and maintenance of the crucial bearing.
