A pitch bearing for coupling a rotor blade to a hub of a wind turbine includes an outer race mountable to the hub and an inner race rotatable relative to the outer race and mountable to the rotor blade. The inner race is formed by first and second ring components, each of the first and second ring components having an outer annular face and an inner annular face. The first and second ring components are joined together at the inner annular faces such that the inner annular faces are opposed and opposite each other. A layer of friction enhancing material is inserted/disposed between the opposed inner annular faces, the friction enhancing material including an abrasive particulate component that increases a coefficient of friction to minimize slippage between the first and second ring components.

In a three row, roller bearing assembly coupling a vessel to a turret, the bearing assembly having a support row assembly disposed between an inner ring connected to the turret and outer rings connected to the vessel, a method and arrangement for in situ remediation of a damaged support row assembly. Couplers are secured to existing inner ring stud bolts. A continuous bearing ring below the couplers is assembled and a support bearing arrangement is installed between the couplers and the bearing ring. Reaction plates are mounted to the vessel. Each reaction plate has a jack screw which is positioned directly below the bearing ring. The jack screws are turned to elevate the bearing ring and form a flat surface for support of the support bearing arrangement. The turret axial load is transferred from the damaged support row assembly to the support bearing arrangement.

A rolling bearing provides an inner ring and an outer ring concentrically about a rotation axis X-X′ running in an axial direction, and at least first and second axial bearings each axially disposed between the inner ring and the outer ring and each having at least one row of rolling elements, the first and second axial bearings being spaced apart from each other in the axial direction. The rolling bearing further provides only one radial bearing radially disposed between the inner ring and the outer ring and having at least one row of rolling elements. The radial bearing is disposed between an outer raceway located on the inner ring and an inner raceway located on the outer ring.

A rolling bearing includes a first ring, a second ring, at least one row of axial rolling elements arranged between the first ring and the second ring, and at least one thrust ring axially interposed between the axial rolling elements and the first ring and delimiting a raceway for the axial rolling elements. At least one spring system axially biases the thrust ring against the axial rolling elements and includes a piston housed in a through-hole of the first ring and a spring element pressing the piston against the thrust ring. The piston includes a threaded hole accessible from outside the first ring.

A rolling-element bearing includes first and second rings having axial and radial raceways and a row of first radial rolling elements between the axial raceways. At least one row of axial rolling elements is located between a first radial raceway of the first ring and a first radial raceway of the second ring and radially located between an axial guiding face of the first ring and an axial guiding face of the second ring. The axial rolling elements are mounted in the pockets of a cage having a plurality of cage segments, and at least one second radial rolling element is circumferentially interposed between two adjacent cage segments of the plurality of cage segments and radially interposed between the axial guiding faces.

An adjusting drive for adjusting the rotational position of a large rolling bearing that comprises two bearing rings that can be rotated relative to each other, having an actuator for rotating the two bearing rings relative to each other. According to the invention, the actuating drive has a ring channel cylinder, which is formed in or on one of the bearing rings of the large rolling bearing, and at least one piston, which is received in the ring channel cylinder in a movable manner and is drivingly connected to the other bearing ring of the two bearing rings.

Provided is a self-aligning roller bearing for supporting a main shaft of a wind power generator, the self-aligning roller bearing including an inner ring, an outer ring, two rows of rollers, and retainers. Each of the rollers has an outer peripheral surface formed with a DLC coating having a multilayer structure. The DLC coating has a film thickness of 2.0 μm or larger. A base material of each of the rollers has an external surface having a surface roughness of Ra≤0.3 and RΔq≤0.05. The DLC coating having the multilayer structure includes layers having stepwisely increasing film hardnesses such that a layer situated closer to outside has a higher hardness.

The invention relates to a seal for a large roller bearing for sealing a joint between two adjacent ring segments or ring parts of the roller bearing, wherein at least two mutually spaced apart sealing limbs of a rubber elastic and/or yielding sealing material for sealing insertion into grooves that are formed at both sides of the joint in ring segments or ring parts that are adjacent to one another and a connection section connecting the sealing limbs and composed of a rubber elastic and/or yielding sealing material to span said joint.

A load cell for determining a radial force acting on a crankshaft includes a receiving sleeve for receiving a ring of a bearing; a fastening ring for attaching the load cell in a transmission housing; axial support areas provided on the fastening ring for axially supporting the ring of the bearing; and measuring regions for receiving radial forces of the receiving sleeve and which connect the receiving sleeve with the fastening ring, wherein strain sensors are attached to at least two of the measuring regions; and wherein the measuring regions comprise measuring lugs formed as angle brackets.
