Roller bearing equipped with a sealing
The invention relates to a rolling bearing equipped with a sealing device having a frame fixed to a first organ. The first organ has a downstream sector bearing a sealing element and presenting a U-shaped geometry formed of an axial bottom surrounded with an inner wall and an outer wall at its edges. The outer wall is extended by a deflector that separates, with the U-shaped geometry, the sealing chamber into an inner compartment and an outer compartment. The bearing also includes a wall fixed to second organ, which presents an outside section forming with the deflector a reduced sealing clearance between the outside opening of the chamber and the outer compartment. The deflector has an outer surface placed in the outer compartment and is slanted towards the opening at an angle β from 10° to 80° relative to a radial direction.
ROLLING-ELEMENT BEARING ASSEMBLY
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.
BEARING WITH AT LEAST ONE SEALING ELEMENT AND AT LEAST ONE ADJUSTING SHIM FOR AXIALLY DISPLACING SAID SEALING ELEMENT
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.
Rolling bearing with flap seal
A bearing includes an annular cup having an outer race and a radially extending flap. The flap defines an inner circumferential surface and a notch extending outwardly from the inner circumferential surface. The notch includes opposing radially extending sides, an outer circumferential wall, and a locking lip raised from the outer wall. Rolling elements are seated on the outer race and arranged to ride on a shaft. A sealing disc has an outer circumferential surface disposed against the inner circumferential surface and a tab received in the notch with the locking lip extending radially over the tab to secure the scaling disc to the cup.
Sealing arrangement for a wheel bearing
A sealing arrangement for a wheel bearing having a first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which rolling elements are guided, wherein the sealing arrangement has a carrier element which is connected to the first bearing part and wherein a resilient element is provided on the carrier element, wherein the resilient element has at least one sealing lip, and the carrier element has a fastening portion which is connected to an outer circumference of the first bearing part, wherein a sealing ring which forms a seal for the fastening portion is formed on the resilient element, wherein the sealing ring has a cylindrical circumferential surface which abuts the external circumference of the first bearing part.
System For Securing Together by Means of Press-Fitting a Casing and a Cover of a Housing Element
A housing element for applications in the manufacturing industry having a casing and a cover both made of metallic material, wherein the casing is provided with a groove and a flat mounting surface and the cover is provided with an end portion having a frustoconical side wall, an oblique annular bottom wall, and a securing system consisting in inserting the end portion of the cover inside the groove of the casing, wherein an interference (i) between a radially outer end of the end portion of the cover and a radially inner end of the flat mounting surface of the casing assumes values of between 0.2 mm and 0.5 mm and an angle () defined between the frustoconical side wall of the end portion of the cover and the flat mounting surface of the casing assumes values of between 45 and 80. The interference and the angle facilitate the insertion of the end portion of the cover inside the groove of the casing.
Slewing bearing with sealing arrangement
A slewing bearing including a first ring, a second ring, the first and second rings being in relative rotation around a rotation axis, at least one row of rolling elements arranged between the rings, and at least one seal mounted in a circumferential groove of first ring. A cap is fixed to the first ring and provides a cap sealing member having an annular heel mounted in an circumferential slot formed on a frontal surface of cap, and a sealing lip projecting from the heel and towards the second ring. The sealing lip has a free end in sliding frictional contact with part of the second ring.
FLANGED INNER RING FOR WHEEL HUB BEARINGS
A flanged inner ring for wheel hub bearings is disclosed, wherein a tubular supporting body for the bearing is coaxial with an axis (X), and is provided with a flange, transverse to the axis (X), is provided with a plurality of threaded through holes distributed around the axis (X), and is axially delimited by an outer annular mounting surface and by an inner surface axially facing an outer ring of the bearing.
WHEEL BEARING ASSEMBLY WITH INTEGRATED SEAL
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.
DOUBLE ROW TAPERED BEARING WITH PRESS FIT PRELOADING ELEMENTS
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.
