Abstract: There is provided a sealing member of a bearing device configured to rotatably support a rotary element relative to a non-rotary element in a rotating device via rolling elements. The sealing member includes a frame mounted on one of the rotary element and the non-rotary element, and an elastic sealing portion attached to the frame. The frame includes a press-fitting portion extending in an axial direction and a flange portion extending in a radial direction from the press-fitting portion. The flange portion of the frame may have a through-hole, the elastic sealing portion may be configured to close the through-hole. At least one perforated-hole may be formed in the elastic sealing portion configured to close the through-hole, and a bearing space, in which the rolling elements are located, may be in communication with an outside via the at least one perforated-hole.

Abstract: A vehicle wheel bearing includes a wheel hub having a hub flange to which a wheel is mounted; at least one inner ring mounted to one side of the wheel hub in a press-fitting manner; an outer ring provided radially outward of the inner ring and having a mounting flange to be mounted to the vehicle body on an outer circumferential surface; one or more rolling elements provided radially inward of the outer ring; and a sealing member configured to prevent foreign matters from flowing into the wheel bearing. The sealing member includes a first sealing member mounted to the wheel hub or the inner ring; and a second sealing member mounted to the outer ring. One or more elastic sealing lips are provided in one or both of the first sealing member and the second sealing member.
