Type thrust ball bearings have an upper and lower complement of angular contact balls and three race elements. Timken designed this type with the capability to carry a thrust load in one direction, comparable to the TVL type, and a lighter thrust load in the opposite direction. 508 mm to 1374.775 mm.

Double direction angular contact thrust ball bearing is made up of an upper component with a larger load carrying capacity and a lower smaller component locked to the machine. The two components are assembled together as a single unit.Double-Direction Angular Contact Thrust Ball Bearings are specially designed high precision bearings for the main spindles of machine tools. Compared with the Thrust Ball Bearings in the 511 Series, this type contains more balls of smaller diameter and has a contact angle of 60°.
