Abstract
A cup bearing includes a cylindrical component having first and second axial ends and defining a lumen therethrough. The cylindrical component includes first and second end portions proximal to the first and second axial ends, respectively. The cylindrical component includes a corrugated portion disposed axially between the first and second end portions. The corrugated portion includes a plurality of corrugations extending radially inwardly. A corrugation of the plurality of corrugations includes a ridge defining a first inner radius of the lumen. The cup bearing further includes a first radial stop associated with the first end portion. The first radial stop defines a second inner radius greater than the first inner radius. The cup bearing also includes an end cap coupled to the second axial end of the cylindrical component.
