Abstract
Abstract This disclosure teaches a cylindrical roller thrust bearing with a roller cage provided on either its inner or outer circumference or on both with a deformable lip the axially outer edges of which are inclined to the axis of rotation of the bearing. Steel discs forming the roller raceway are held in place by the lip which is inserted in snap-like fashion. The steel discs are provided preferably at their outer circumferences with a burr over which an edge of the lip engages and a rounding axially outward of the burr to receive the edge. The steel discs may each be borne by a plastic ring which is supported and held by a bead formed in its outer circumference and engaged behind the lip.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
113 words
A cylindrical roller thrust bearing comprising in combination: a pair of substantially planar discs of about the same size and spaced parallel each to the other with each normal to and positioned about a common axis, a ring of rollers positioned in a cage member between the diScs with each of the rollers arranged radially relative the axis and with the discs providing a raceway for the rollers, each of the discs having a margin, said bearing cage having an elastically deformable lip surrounding the margin with edges and having an extended condition in which the edges fit snugly over the margins so that the discs and rollers thereby are held in position.
Claim 2
Dependent Claim
