A secondary sealing device is for a wheel bearing assembly including a fixed inner axle with an outer circumferential surface and a bearing inner race, an outer hub rotatable about the inner axle and having an inner circumferential surface and a bearing outer race, rolling elements disposed between the inner and outer races, and a primary seal(s) connected with the inner axle and sealingly engaged with the outer hub. The secondary sealing device includes a rigid annular body having an inner radial end coupled with the inner axle and an outer radial end spaced radially inwardly from the inner circumferential surface of the outer hub so as to define an annular gap between the body and the outer ring. The body is located between the primary seal and an axial end of the hub so as to provide a barrier configured to prevent contaminants from contacting the primary seal.

A rotary suspension stop for a suspension strut comprises a bearing, a lower support forming a bearing surface for an upper turn of a helical spring and an annular shrink-fitting surface turned radially in a radial reference direction, a cover comprising an annular skirt extending axially facing and at a distance from the shrink-fitting surface and a seal having a body, at least one annular sealing lip in sliding contact against the annular skirt of the cover and at least a first set of one or more elastic first shrink-fit lips projecting toward the shrink-fitting surface and shrunk to the shrink-fitting surface.

A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.

A dry-lubricating apparatus, for press fitting onto a mating part, includes (a) a frame, (b) a rubber gasket fixed to the frame to create an interference with a mating surface of the mating part so as to enable the press fitting, and (c) a lead-in edge fixed to at least one of the frame and the rubber gasket. The lead-in edge includes a dry lubricant such that, when the dry-lubricating apparatus is slid onto the mating part, along the mating surface and with the rubber gasket trailing the lead-in edge, a portion of the dry lubricant is abraded off the lead-in edge to reduce friction between the rubber gasket and the mating surface.

A bearing providing a first ring assembly and a second ring assembly, the first ring assembly including at least a first ring and an outer cap reversibly fixed to first ring. The bearing further providing at least one sealing element mounted radially into a cylindrical surface of the first ring assembly and provided with a sealing lip in sliding frictional contact with the second ring assembly. The bearing including at least one adjusting shim mounted radially between the first and second ring assemblies, the adjusting shim being axially located between the outer cap of the first ring assembly and the sealing element; or between the first ring of the first ring assembly and the sealing element.

A seal ring (26) configured to be employed with a cross shaft (16) including a center section (17) and four shaft sections (18a, 18b, 18c, 18d) extending in four directions from the center section and formed with step faces (17a) where the center section widens out from base ends of the shaft sections outward in radial directions of the shaft sections, and with bearings (21) for mounting to leading end portions of the shaft sections. The seal ring is fitted over the shaft section and interposed between the bearing and the step face. The seal ring includes a seal lip (34) configured to contact the step face around the entire circumference, and an indentation (36) the seal lip enters by deforming when mounted to the cross shaft.

A seal assembly is for sealing a bearing disposed between an inner shaft and an outer hub and includes an annular inner case having an axial section disposable about the shaft shoulder and a radial section extending radially outwardly from the axial section. An annular outer case is disposed about the inner case, has an axial section coupleable with the hub and a radial section extending radially inwardly from the outer case axial section and spaced axially from the inner case radial section. An elastomeric seal member is attached to the outer case radial section and has a sealing lip sealingly engaged with the axial section of the inner case. An annular positioner is coupled with the inner case and has a radial section engageable with the axial end of the bearing inner ring so as to locate the inner case at a desired position along the central axis.

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 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.
