An axial seal assembly includes an inner annular shield having an axial portion disposeable about the shaft at a position adjacent to the bearing and a radial portion extending radially outwardly from the axial portion. An outer annular seal has an axial portion engageable with the outer member bore, a radial portion extending radially inwardly from the axial portion and on or more axial sealing lips engaged with the shield radial portion. The seal radial portion is spaced from the shield radial portion by a predetermined axial distance during use. The seal has at least one coupler section engageable with the shield radial portion or the shield axial portion when an axial spacing distance between the seal radial portion and the shield radial portion is less than the predetermined distance to retain the shield coupled with the seal when the seal assembly is separate from an outer member bore.

A wheel bearing assembly includes a fixed inner axle with at least one inner race, a rotatable outer hub disposed about the axle and having at least one outer race and rolling elements disposed between the inner and outer races. An annular seal is disposed between the axle and the hub and is located adjacent to the inner and outer races. A shield is spaced axially from the seal such that the seal is disposed between the rolling elements and the shield. The shield includes a rigid annular body having an outer radial end coupled with the outer hub, preferably by a plurality of couplers, and an inner radial end defining a central opening for receiving the axle and located adjacent to the inner axle or a component disposed upon the axle. As such, the annular body substantially obstructs an annular interior space to prevent substances from contacting the seal.

A seal assembly is for a wheel bearing assembly including an inner axle and a rotatable outer hub disposed about the axle. The seal assembly includes an annular inner case having an axial portion disposeable about the axle and a radial portion extending radially outwardly from the axial portion. A seal is coupled with the hub and has sealing lip(s) sealingly engageable with the annular case. Further, an annular flinger has an inner radial end coupled with or integrally formed with the annular inner case and an outer radial end including an outer axial portion spaced radially inwardly from the inner circumferential surface of the hub so as to define an annular labyrinth gap. The flinger includes a central portion that is at least partially frustoconical and extends between the inner and outer axial ends so as to obstruct an annular space between the inner case and the seal.

A rolling bearing 1 includes an outer ring 1A, an inner ring 1B, a plurality of rolling elements 1C, and a seal member 1D. The outer ring 1A includes a first outer ring 10 and a second outer ring 20. The inner ring 1B includes a first inner ring 30 and a second inner ring 40. The seal member 1D includes an annular base portion 61, 71 fixed to one bearing ring which is one of the outer ring 1A and the inner ring 1B, and an annular protruding portion 62, 72 protruding from the base portion 61, 71 and extending toward a first region which is a region opposing the one hearing ring in another bearing ring which is the other of the outer ring 1A and the inner ring 1B.

A sealing device has two sealing members. A first sealing member has a cylindrical mounted part adapted to be mounted to an outer member and an annular part extending radially inward from the cylindrical mounted part toward the inner member. A second sealing member has a sleeve adapted to be mounted to an inner member, a flange extending radially outward from the sleeve, and a cylindrical protruding portion made from an elastic material extending along the axial direction from the flange. Multiple retaining protrusions are formed on the inner peripheral surface of the cylindrical mounted part of the first sealing member are arranged at intervals in a circumferential direction. On the outer peripheral surface of the cylindrical protruding portion of the second sealing member, circumferential groove extending continuously in a circumferential direction is formed, within which the retaining protrusions are placed.

A rotation induction device for a vehicle includes: an upper case having a piston rod disposed therethrough; a lower case disposed adjacent to the upper case and having the piston rod disposed therethrough; a center plate disposed between the upper case and the lower case such that the piston rod passes through the center plate, to induce rotation of one or both of the upper case and the lower case; and a friction restraint part formed on one or both of the upper case and the lower case, to restrain friction with the center plate.
