Thrust Needle Roller Bearing with raceway washers for oil flow control
The outer race of the bearing is designed to improve the ease of flow of the AT oil into the bearing. Also, holes have been added in the cage to improve oil flow. As a result, oil penetration into the bearing is 1.5 times that of the conventional part. Optimizing the balance of oil supply in the AT unit in this manner makes it possible to reduce the size of oil pumps.
　The newly developed partial curl type race has an integrated design that partially holds the bearing components(roller, race, cage) and improves the inner clearance of the bearing, thereby improving the durability in regard to the concern of eccentricity(axial offset) that exists with integrated thrust needle bearings.
