A bearing sealing device includes two seals (inner and outer seals) sealing the space between the inner and outer races of a bearing to ensure higher seal performance, and also to reduce the area of the inner periphery of the outer race that needs to be ground. The bearing sealing device includes a ring constituted by a metal annulus, and a rubber part. The metal annulus is formed by cold pressing, and has a seal contact surface kept in contact with seal lips of the outer seal. The rubber part includes a press-fitted portion fixed to the inner periphery of the outer race. The inner race has, on its outer periphery, a cylindrical fitting surface to which the outer seal is press-fitted.

A roll device as a spreader roll has a rotating hollow roll tube which at the ends thereof is rotatably mounted by means of bearing ends which are mounted in rotary bearings. The roll device has a tension element which runs so as to be eccentric to the central longitudinal axis of the roll tube through the roll tube and by internal tension toward the ends of the roll tube is impinged by a force with pressure. As a result, the roll tube is capable of being bent by way of an impingement of the tension element with a force, the deflection being transversely away from the longitudinal extent of said roll tube, if the tension element is tensioned in relation to the roll tube in an axial direction.

A bearing assembly includes a housing having a flange at a first axial side and a bearing attachment section at a second axial side and a rolling-element bearing having inner and outer rings and a plurality of rolling elements. The rings are sealed on first and second axial sides by first and second seal disks, and the outer ring is pivotably mounted in the attachment section of the housing and the inner ring is configured to be mounted on a shaft. The assembly also includes a seal assembly configured to form a seal between the flange and the shaft at the first axial side of the housing, an end cover, an O-ring compressed between the second axial side of the housing and the end cover and at least one seal barrier between the seal assembly and the first seal disk and/or between the cover and the second seal disk.

A system for lubrication of a bearing of a crop transport and/or processing system of a harvesting machine includes a supply container for storing a lubricant, means for delivering the lubricant from the supply container to the bearing, and means for returning the lubricant from the bearing to the supply container.

A bearing unit (10) has a radially outer ring (31), a radially inner ring (33), an eccentric locking collar (40), a row of rolling bodies (32), and a sealing device (50). The sealing device (50) is arranged on the same side as the locking collar (40) and is interposed between the radially inner ring (33), the radially outer ring (31) and the locking collar (40). The sealing device (50) includes a metal shield (55) stably connected to the radially outer ring (31), and an elastomeric component (60) co-molded on the shield (55) in a radially inward direction. The elastomeric component (60) has a plurality of lips, of which at least one lip (64, 65) is in contact with the locking collar (40).

A bearing retainer for use in a bearing is provided. The bearing includes an inner ring, rolling elements and an outer ring. The bearing retainer has a body. The body defines an inner periphery and an outer periphery of the body. The body further defines a plurality of openings extending from the inner periphery to the outer periphery of the body. The plurality of openings are adapted to retain the rolling elements in a spaced apart relationship. The body further defines opposed faces extending from the inner periphery to the outer periphery of the body. The body further defines a plurality of face pockets formed in at least one of the faces of the body. The face pockets are adapted to storing lubrication. The body further includes a pathway from at least one face pocket of the body to the inner periphery of the body.

An assembly for a turbomachine includes a fan rotor drive shaft, a rolling element and a support of an exterior rolling-element bearing ring including an exterior annular element as well as an interior annular element coupled through a decoupling interface in the shape of a truncated sphere and configured to be retained by friction under normal operating conditions of the turbomachine, and to move with respect to one another in the event of a fan blade loss. The rolling-element bearing is designed so that each rolling element has four points of contact with the rings, and so that the interface between the ring and the support has a hollowed space for deformation routed around a central portion of the exterior ring.

A bearing unit having a stationary radially outer ring, a radially inner ring rotatable about a central rotation axis (X) of the bearing unit is provided with at least one raceway and, in an end portion thereof, with at least two circular sector segments, at least one row of rolling elements interposed between the radially outer ring and the radially inner ring, and a concentric collar for clamping the radially inner ring on a rotating shaft, where an induction-hardening heat treatment is applied to a portion of the radially inner ring that overlaps with at least a portion of the at least one raceway.

A bearing seat suitable for receiving a bearing includes an annular body, a first outer-radial flange and a second outer-radial flange. The annular body includes a peripheral wall. The peripheral wall has a first end, a second end, an inner matching surface and an outer surface. A thickness difference between the maximum thickness and the minimum thickness of the peripheral wall is within 30%. A portion of the inner matching surface is suitable for contacting and matching with an outer matching surface of the bearing. The first outer-radial flange protrudes from the outer surface adjacent to the first end and extends to the first end. The second outer-radial flange protrudes from the outer surface adjacent to the second end and extends to the second end. The overall structure of the bearing seat is uniform, which can reduce warpage and deformation caused by uneven shrinkage during the injection process.

A bearing arrangement for use with a structure defining an outer surface which expands and contracts inward and outward relative to the structure includes, a member having at least one inner surface to face the outer surface, and at least one protrusion extending from the inner surface, the at least one protrusion being biased toward and in contact with the outer surface and maintains contact as the structure expands and contracts.
