Abstract: The performance of a long life anti-wear motor bearing grease was investigated. Comparative test analysis of infrared spectrum, high pressure differential thermal scanning and SRV was carried out on grease after 518 hours. The analysis results show that the overall performance of the developed long-life anti-wear bearing grease has little change from that of the unused long-life anti-wear motor bearing grease after being used for 518 h, and the grease still has excellent oxidation resistance and anti-wear performance, which is superior to Russian СЭДА grease.

Key words: grease, bear, anti- frication, dynamotor, long life
