An axially supporting rolling-element bearing of a rolling mill shaft includes an inner ring having a raceway, an outer ring having a raceway and a plurality of rolling elements on the raceways between the rings. An outer surface of the outer ring includes an opening such as a groove that faces radially outward and contains a seal element. The seal element includes a seal lip that extends out of the groove. When the rolling element bearing is placed in a bore of a housing, the outer ring is spaced from the bore by the seal element.

A UTV double row tapered wheel bearing assembly may include a first inner diameter race, a second inner diameter race axially offset from the first inner diameter race, and an outer diameter race radially offset from the first inner diameter race and the second inner diameter race, the outer diameter race formed as a single integral member. A first ring of rollers may be disposed between the outer diameter race and the first inner diameter race. A second ring of rollers may be disposed between the outer diameter race and the second inner diameter race. A first shield may be coupled to a first axial face of the bearing, and a second shield may be coupled to the second axial face of the bearing.

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.

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.

Linear motion mechanism sealants capable of operating at low torque when engaging in linear motion which are capable of carrying out sealing with respect to fine particulate several μm in diameter, and which are side seal units for sealing gaps at a shaft provided at a front end portion and a back end portion of a slider of a linear motion mechanism equipped with said shaft and said slider which carries out reciprocating linear motion on said shaft, the linear motion mechanism side seal units 4 being characterized in that fibrous surfaces of seal members comprising fibrous material are arranged so as to be directed toward said shaft in such fashion as to abut and conform to the cross-sectional shape of said shaft at the front end portion and the back end portion of the slider.

A sealing device for sealing a gap between inner and outer members includes a mounted part attached to a cylindrical end of the outer member; at least one lip disposed radial inside the mounted part and extending toward the inner member; an annular part covering an end surface of the end of the outer member; and an annular flange formed from an elastic material connected to the annular part and disposed radial outside the end of the outer member. The inner member includes an inner portion disposed radial inside the outer member; a flange extending radially outward from the inner portion; and a through-hole formed in the flange for inserting a screw for securing the inner member to another member. The outer edge of the flange of the sealing device is disposed radial outside a portion of the through-hole that is the closest to the central axis.

A seal assembly is for sealing a space adjacent to a bearing and defined between an inner member and an outer member disposed about the inner member. The seal assembly includes an annular seal disposed about the inner member and having a sealing lip sealingly engageable with the inner member. An annular load ring is disposed within the outer member bore and has an inner circumferential surface defining a bore, the seal being disposed within the bore and coupled with the ring. A first axial end of the ring is disposed against the bearing outer ring, or a spacer disposed axially between the load ring and the bearing outer ring, and a second axial end is disposed against a radial surface of the outer member. The load ring is configured to support axial loading on, and to prevent axial displacement of, the bearing outer ring.

Seal assemblies, gaskets, bearing assemblies, and their components can be used as pre-packaged seal systems and pre-packaged seal and bearing systems. The seal assemblies can be orientated in different configurations for different applications. Gaskets to restrict flow and gaskets with memory lips to operate as sealing lips can be included to increase the number of sealing points. In a pre-packaged configuration, the cylinder can be a straight cylinder, a stepped cylinder, or a split cylinder. Bearing assemblies can be pre-packaged with the sealing assemblies and service grease may optionally be used to provide lubrication and limit fluid incursion into the spring cavities.

A rolling-element bearing assembly includes a first bearing ring and a second bearing ring that define a bearing interior between them, a plurality of rolling elements disposed in the bearing interior to allow a relative rotation of first and second bearing rings, and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier that is connected to the first bearing ring such that they rotate together and a seal element that is connected to the seal carrier such that they rotate together, and the seal carrier comprises a fiber-reinforced plastic.

Wheel bearing assembly for motor vehicles, the assembly being provided with a wheel hub and a bearing unit in turn provided with a radially outer ring and at least one radially inner ring provided, respectively, with a first raceway and at least one second raceway, with at least one row of rolling bodies arranged between the radially outer ring and the at least one radially inner ring, and with a cage for containing the at least one row of rolling bodies; the wheel bearing assembly is moreover provided with sealing means integrated in the cage and provided with at least two radial contact lips made of elastomeric material, with at least one first radial lip in contact with the radially inner ring and with at least one second radial lip in contact with the radially outer ring.
