There is provided a wheel bearing sealing arrangement for a wheel bearing of a vehicle, comprising an outboard bearing having an outboard periphery intended to face away from a central longitudinal axis of the vehicle and an inboard periphery intended to face towards the central longitudinal axis of the vehicle, wherein the outboard bearing comprises a first race-forming part and a second race-forming part which surrounds the first race-forming part; an outboard seal arranged between the first race-forming part and an opposite part; and a safety washer pressed against the outboard periphery of the first race-forming part, wherein the outboard seal comprises a sealing part pressed against and in direct contact with the safety washer. There is also provided a vehicle comprising such a wheel bearing sealing arrangement.

A support assembly for movable, rotating or sliding shafts, having a bearing unit having an inner ring, an outer ring, and a row of rolling bodies interposed between the inner and outer rings, a casing, a cover for fluid sealing an opening of an internal seat of the casing, a rear sealing device on a side opposite the cover having a metal screen and a vulcanized rubber liner equipped with an axially outer first sealing lip and with an axially inner second sealing lip, an axially inner sealing device, having a first shield provided with a vulcanized rubber liner having a plurality of sealing lips, the outer ring having a step extending axially inward and provided with a second shield having a vulcanized rubber liner with a plurality of sealing lips.

A bearing unit having a stationary radially outer ring, a radially inner ring, rotatable with respect to a rotation axis (X) and steadily connected to a rotating shaft, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, a casing, inside which the rings of the bearing unit are housed, a sealing device, and a protection disk. The protection disk may be mounted in an axially external position to the sealing device and fixed to the radially inner ring. Additionally, the protection disk may have a shaped metallic screen, and an elastomer coating over-molded on part of the screen. The protection disk may further be in contact with an axially external surface of the radially outer ring through the elastomer coating, which is provided with two lips, a first lip, non-contacting or contacting and radially external, and a second lip, contacting and radially internal.

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 for sealing a grease lubricated large rolling-element bearing includes a radial shaft seal having at least one seal lip configured to sealingly abut against a shaft to seal a bearing interior and substantially prevent a grease discharge from the bearing and a grease flow regulation device, such as an annular pumping ring, for regulating a grease pressure at the at least one seal lip, the grease flow regulation device being mounted adjacent to the radial shaft seal at a side of the radial shaft seal that is intended to face the bearing interior in an installed state.

A rolling-element bearing unit for a wheel bearing assembly of a vehicle includes a first rolling-element bearing having an outer bearing ring and an inner bearing ring and rolling elements disposed between the outer bearing ring and the inner bearing ring and a first seal element having a seal-element base body having a first support member mounted to an axial outer surface of the inner bearing ring and a first seal lip pressed against a radial end surface of the outer bearing ring to hold the outer bearing ring in position relative to the inner bearing ring. Also a wheel bearing assembly including two such rolling element bearing units.

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.

Provided is a hub unit bearing wherein a cover can be firmly fitted with an outer ring member, and it is difficult for foreign matter to enter inside through a water drainage hole formed in the cover. The cover that covers the inside end section in the axial direction of the hub unit bearing includes a disk section, a small-diameter cylindrical section bent in the axial direction from the outer perimeter edge section of the disk section and a large-diameter cylindrical section. A cut and raised section that is cut and raised toward the inside in the radial direction is formed in the small-diameter cylindrical section, and a water drainage hole that passes through from inside to outside the cover is provided in the portion that is cut and separated from the small-diameter cylindrical section.

A compact bearing unit (1) for a double disc coulter (2) with ball bearing (23) with an inner ring (3), outer ring (5) with flange facing and a protective cap (7) has a multi-stage sealing system. A first seal (11) is provided between the inner ring 3 and an internal ring race (17) of the outer ring (5). At least one additional seal (14) is arranged between the protective cap (7) and a ring race (13, 17) of the outer ring (5), whereby said seal does not make any additional installation space necessary in the axial direction of the bearing unit (1).
