| Abstract | Bearings have seals that keep lubricating grease inside, as well as that protect their bearing raceways from dirt and foreign particles. These bearing seals are particularly important functional components for automobile axles that are used in harsh environments. As the global automobile market has been expanding into extremely cold area and inland of continents regions, the environments for axle bearings have been becoming even more severe. With the aim of global standardization, JTEKT has developed a new seal which can withstand harsh environments without increasing sliding torque. |
