A sealing assembly for bearings, in particular for use in agriculture, comprising a primary sealing barrier and a secondary sealing barrier, which are arranged in series along a potential path (P) of ingress of contaminants into the bearing, and have, respectively, a first seal and a second seal with a plurality of contact lips. The contact lips of the first and second seal with a plurality of contact lips may be static lips that do not rotate about an axis (A) of rotation of the bearing.

A temperature-robust polymer shroud for a roller bearing seal includes a shroud body and an inner diameter leg defining respective portions of a single continuous part. The shroud body encircles a rotation axis of the polymer shroud and extends predominantly in directions orthogonal to the rotation axis from an inner diameter to an outer diameter. The inner diameter leg connects to the shroud body at the inner diameter and encircles the rotation axis, wherein, along the entire inner diameter of the shroud body, the inner diameter leg is oriented at an oblique angle to the rotation axis to extend both (a) radially inward from the inner diameter and (b) axially away from the inner diameter along a first direction parallel to the rotation axis. A roller bearing seal includes a seal case, an elastomer lip, and the temperature-robust polymer shroud.

A hub bearing assembly includes a housing with a vertical bore, a bearing outer ring disposed within the bore and coupled with the housing and a bearing inner ring disposed within the bearing outer ring and having a central bore configured to receive a portion of the shaft. A set of rolling elements are disposed between the bearing outer and inner rings. An upper seal is disposed within the housing bore externally of the outer ring and includes an annular elastomeric seal body and a garter spring biasing a seal lip radially inwardly. A lower seal is disposed between the bearing outer and inner rings. Either the bearing inner ring is sized such that upper seal is disposed about the bearing inner ring or the hub bearing assembly further comprises an annular spacer disposed within the upper seal and adjacent to the upper axial end of the bearing inner ring.

Wheel hub unit provided with a radially outer ring, stationary in use, a radially inner ring, rotating in use, at least one row of rolling elements, interposed between the radially outer ring and the radially inner ring, and a seal assembly, interposed between the radially outer ring and the radially inner ring, which defines cooperating with the radially outer ring or with the radially inner ring a shield of at least one labyrinth seal. The labyrinth seal does not have a circumferential symmetry but comprises an upper portion and a lower portion with respect to a symmetry axis (A) of the wheel hub unit and is provided with an angular interruption of the shield made on its lower portion corresponding to the lower side of the wheel hub unit so as to increase an outflow section thereof from the labyrinth seal itself which facilitates gravity drainage of contaminants present inside the seal assembly.

A seal structure of a drive device is provided which includes a case in which a motor chamber for accommodating an electric motor and a gear chamber for accommodating a gear mechanism are located adjacent to each other, a partition that separates the motor chamber and the gear chamber, a bearing that supports a rotating shaft, a seal part that seals between the rotating shaft and the partition, a lubricating oil that lubricates the gear mechanism, and a coolant that cools the electric motor, and also includes a first bearing on the motor chamber side, a second bearing on the gear chamber side, a first seal part on the motor chamber side, a second seal part on the gear chamber side, and at least the second seal part of the first seal part and the second seal part is provided between the first bearing and the second bearing.

A bearing provides a first ring and a second ring capable of rotating concentrically relative to one another, and at least one seal provided with at least one sealing lip. The bearing further includes a sealing module providing a carrier reversibly secured to the first ring, the seal being mounted radially into contact with the carrier, a friction ring reversibly secured to the second ring, the sealing lip of the seal coming into contact with the friction ring, and at least one spacing element axially interposed between the friction ring and the second ring.

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 dry vacuum pump is provided, including an oil sump; a pumping stage; two rotating shafts respectively holding a rotor extending in the pumping stage, the rotor being configured to rotate in a synchronised manner in opposite directions in order to carry a gas to be pumped between an intake and a discharge of the pump, the two rotating shafts being supported by bearings lubricated by a lubricant contained in the oil sump; and a lubricant sealing device inserted between the oil sump and a pumping stage at each shaft passage, the sealing device including a disc-shaped deflector mounted on a shaft of the two rotating shafts for rotation therewith, and a disc of the deflector has an annular end on a periphery thereof, extending towards the pumping stage, forming a retaining recess.

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.

An integrated seal and bearing assemblies with a bearing assembly having an outer ring defining an outside diameter of the bearing assembly and an inner ring defining an inside diameter of the bearing assembly, and having a plurality of rolling elements located between the inner and outer rings. A seal assembly having a sealing element is integrated with the bearing assembly by engaging an extended flange with an internal channel of the seal element, with a sealing extended flange, or directed with complementary surfaces of the outside flange.
