A rolling-element bearing assembly includes first and second bearing rings that form a bearing interior between them and a plurality of rolling elements disposed in the bearing interior and a seal assembly for sealing the bearing interior. The seal assembly includes a seal carrier and a seal element having at least one primary seal lip for sealing the bearing interior and a secondary seal lip for sealing against external contamination. The seal element is connected to the seal carrier such that the primary seal lip and the secondary seal lip abut axially against an axial end surface of the second bearing ring.

Disclosed is a bearing assembly, in particular a large bearing assembly, including at least one inner ring and at least one outer ring, between which at least one circumferential seal is disposed that slips on a circumferential slip surface of the inner ring or of the outer ring, wherein guide channels are formed on the slip surface or the circumferential seal.

A sealing device including a first annular shield fixable to a first ring, a second annular shield facing the first and fixable to a second ring. A first shield annular sliding sealing lip cooperating with the second ring. At least first and second annular non-contacting sealing lips of the second shield. The first non-contacting lip includes a first portion extending in projection, and a second end extending axially and radially projecting from the first portion; being tapered towards a free end thereof, axially away from the first ring, which come into contact axially when the first annular lip is bent towards the first shield. The second non-contacting lip extends axially projecting from the first shield from the same side as the second portion of the first lip and beyond it and forms towards the first lip an annular collecting channel of possible contaminants which pass beyond the first annular lip.

The present invention achieves construction for a seal ring-equipped ball bearing (1a) that allows the outer-diameter dimension of a load-bearing surface (35a) to be made large, allows a large contact area with a transmission gear (16) to be secured, and allows dynamic torque to be reduced. Seal lips (14a) of seal rings (4a) that cover opening sections on both sides of the seal ring-equipped ball bearing (1a) have a substantially horizontal V-shaped cross-section and are configured so that an outer-diameter-side inclined section (25) and an inner-diameter-side inclined section (26) are connected by a continuous portion (27). The inner-circumferential edge section of the inner-diameter-side inclined section (26), which is the tip-end edge of the seal lip (14a), is made to slide over the entire circumference of the outer peripheral surfaces of both end sections of an inner ring (8a), the end sections being cylindrical surfaces (30) without seal grooves. The angle (α.sub.1) of an inside-continuous surface (29) of the continuous portion (27) is at least 104°, and the overall length of the inner-diameter-side inclined section (26) is kept long by the continuous portion (27) entering radially inward into a wave-shaped retainer (10a).

A seal arrangement for sealing a radial gap between an inner component and an outer component coaxially mounted around the inner component is provided. The inner component rotates about a rotation axis. The arrangement provides a radial seal connectably mounted to the inner component. The radial seal has a sealing lip that bears against a counterface formed by a radially inner surface of the outer component. When the seal arrangement is stationary, the sealing lip bears against the counterface with an initial lip force. The sealing lip is pivotably arranged in a radial cross section around a pivot point, and is in connection with a counterweight. The sealing lip and the counterweight are arranged in different axial regions from the pivot point and are adapted such that during rotation of the radial seal, a greater centrifugal force acts on the counterweight than on the sealing lip.

The bearing provides an outer ring, an inner ring, at least one seal to one of the rings and cooperating with the other ring, and at least one sealing flange. The sealing flange includes a fixing portion to fix the flange to the other ring, an end portion and a connecting portion to connect the fixing portion and end portion. The end portion of the flange is curved and disposed axially facing the connecting portion. The curved end portion and connecting portion define an annular space that open radially towards the other ring. The curved end portion is mounted axially in contact against an outer lateral face of the seal.

The present invention relates to a pressure roller bearing for a pallet car of a pelletizing machine. The bearing includes an external annular race having: an exterior surface for reversible mating engagement with a tooth gap of a wheel, a pair of sidewalls defining ends of the bearing, wherein the radial diameter of the exterior surface at a center portion in the axial direction is greater than the radial diameter of the exterior surface at the ends of the bearing, and an interior annular groove; an internal annular race defining a hole therethrough for receiving an axle, and having an exterior annular groove; and a plurality of rolling cylindrical members located in an interior space defined by the interior annular groove and the exterior annular groove when the internal annular race is received by the external annular race.

Provided is a bearing unit for a rotor unit of a wind turbine, including a first bearing ring, a second bearing ring, a plurality of rolling elements and a sealing member including a sealing member base portion, a first sealing member tip portion and a second sealing member tip portion, wherein the first sealing member tip portion abuts a first wall of the first bearing ring and the second sealing member tip portion abuts a second wall of the bearing unit, wherein the sealing member is configured and arranged such that a first contact pressure between the first sealing member tip portion) and the first wall is transmitted through the sealing member to the second sealing member tip portion to increase a second contact pressure between the second sealing member tip portion and the second wall. Also provided is a wind turbine.

A contamination-resistant bearing assembly includes an inner ring, an outer ring, a rolling unit, two contamination-resistant internal sleeves and two contamination-resistant external sleeves. The outer ring cooperates with the inner ring to define a bearing space where the rolling unit and the sleeves are disposed. The external sleeves are located at two opposite sides of the internal sleeves which are located at two opposite sides of the rolling unit in an axial direction. Each of the external sleeves includes a metal rigid shell and a sealing member.

A seal arrangement for a wheel bearing having first bearing part and a second bearing part integrally connected to a wheel bearing flange, between which bearing parts rolling elements are guided. The sealing arrangement includes: a carrier element, which is connected to the first bearing part and an elastic element is provided on the carrier element. The elastic element has at least one sealing lip, and the carrier element has a fastening section, which is connected to the first bearing part. A stop part is fastened to the second bearing part with which the at least one sealing lip is in rubbing contact. The wheel bearing flange has an axial projection at least partially surrounds an axial projection of the first bearing part, and an inner surface of the axial projection of the wheel bearing flange forms a seat for the stop part.
