Patent Abstract / Summary
[0001] A bearing (100) comprises a first half shell (110) and an eccentric second half shell (140), in which the first and second half shells are configured to connect at a joint (125) to form a cylindrical bearing. The first half shell has a first crown thickness at a crown of the first half shell, and a first wall thickness between the crown and the joint. The second half shell has a second crown thickness at a crown of the second half shell, and a second wall thickness between the crown and the joint. The second crown thickness is greater than the first crown thickness, and the first wall thickness is equal to the second wall thickness at a point of equal thickness between 10 and 60 degrees from the joint. A method of manufacturing the bearing is also provided.
