Thrust bearing in the installation position of the engine and torque converter, usually installed in the engine and torque converter in the eccentric conditions. If not allowed to eccentric bearing ring guard and retainer contact heat, resulting in wear. Therefore, on the market (1) allows a large eccentricity, long life; (2) for embedding considerations bearing ring and the cage to achieve the integration of the two. But the old structure of the bearings is unable to meet these two functions. Or even allows a large eccentricity, but the structure remains separate type; either one structure, but does not allow large eccentricity.

Eccentric bearing ring of a body thrust needle roller bearings in a body structure of the bearing ring at the same time, by taking the following three measures to achieve a long life:

(1) To make the bearing retainer and bearing ring radius direction on the gap set volume than eccentric, internal structure has been improved; 

(2) Using fem analysis, to optimize the shape and thickness, increase cage strength;

(3) In order to prevent the lubricating oil to reduce surface damage caused by the design guide groove in the bearing ring. In addition, its body structure is achieved through the use of the bearing ring crank claw structure and inlay buckle structure. By reducing the number of components to a minimum, not only control costs, and also easier for customers to carry out
