Abstract
A wheel bearing assembly endcap 200 configured with a pilot structure 202 defined by radially-inner and radially-outer annular portions 202a, 202b joined by an annular bend 202c disposed between a central face 204 of the endcap and an outer peripheral flange 206. The pilot structure 202 projects in an axially outboard direction along the axis X of the wheel bearing assembly 100 for fitment within an inner diameter surface 112 of an outer axial member 106, to facilitate sealing and a spring-biased retention of the endcap 200 within the wheel bearing assembly 100. The outer peripheral flange 206, which is contiguous with the pilot structure 202, seats against an inboard end face 114 of the wheel bearing assembly 100 outer axial member 106 to provide a positive axial stop, and is configured as an additional sealing element to reduce contaminate ingress between the endcap 200 and the interior surfaces of the wheel bearing assembly 100.
