| Abstract | Four-stroke engines have been widely used in motorcycles and special vehicles in order to meet emission control regulations and improve fuel effi ciency. Lubricating oil is fed by an oil pump to the four-stroke engine, and a ball bearing with integrated oil pressure resistance seal is used at the oil pathway of the shaft end as an oil pressure bulkhead. As a result of improvements in engine performance, demands for higher speeds, higher pressures and improved sealing performance have increased. To meet these demands, we have developed a ball bearing with integrated high oil pressure resistance seal. This report describes this development. |
