  • Publication number: 20250243910
    Abstract: A universal joint bearing includes a trunnion, a cup, rolling elements rotatably supporting the cup relative to the trunnion, and at least one seal for sealing a space between the trunnion and the cup. The cup has a substantially cylindrical surface, which is a part of a radially outer surface of the universal joint bearing. All of the rolling elements of the universal joint bearing are arranged in a certain number of rows of rolling elements. A sum of the maximum axial lengths of all the rows of rolling element divided by the sum of the maximum axial length of the substantially cylindrical surface and the maximum axial length of a radially outer surface of the at least one seal, which is another part of the radially outer surface of the universal joint bearing, is between 0.6 and 0.75.
