Using cassette oil seal structure and HNBR as the base rubber,the effects of silica and vulcanizing agent dosage on the hardness,100%modulus,radial force of oil seal,dry friction perform-ance and working life of HNBR rubber were studied,and the optimal rubber hardness and vulcaniza-tion system dosage were determined.The results showed that when the hardness was Shore A 72 and the dosage of vulcanization system was 11 phr,the cassette oil seal had no oil leakage after the 5000 h working life test,and its main size and radial force changes were small.
