A bearing housing is provided with a cooling channel in at least part of the circumference around the bearing. The cooling channel is provided with a flow guide member at least in part of its flow section to construct a tortuous passage whose flow distance is longer than the corresponding circumferential length of the flow section. On the basis of the above-mentioned bearing housing, the present invention also provides a bearing housing unit, a continuous casting roll line and a continuous casting machine that use the bearing housing. The above-mentioned bearing housing adopts an optimized cooling channel design, which can obtain a better cooling effect without changing other structures of the bearing housing. Therefore, it is particularly suitable for upgrading existing equipment and has a huge cost advantage and a wide range of application prospects.

An angular contact self-aligning roller bearing, including rollers, an inner ring, a cage, an outer ring, an outer raceway and an inner raceway. The outer raceway is an inner spherical surface. A spherical center of the inner spherical surface is located on an axis of the outer ring and deviates from a central point of the outer ring. The rollers are in a single row. A working surface of each roller is an externally convex surface, which is formed by rotation of a first circular arc as a generatrix around an axis of each roller as a rotation axis. The inner raceway is an internally concave surface, which is formed by rotation of a second circular arc as a generatrix around an axis of the inner ring as a rotation axis. The bearing can withstand separate loads or combined loads in axial and radial directions, and adapt to misalignment.

A bearing, in particular to a self-aligning roller bearing, with a fastener of a sealing disc, which fastener increases the load-bearing strength. The bearing includes a bearing ring with an annular sealing disc which is connected to one of the two bearing ring end surfaces by a fastener which have a shank and a head, which has an enlarged diameter with respect to the shank, and the respective shanks reach through the bores which are made in the respective end surface. Here, the annular surfaces have a cylindrical contour, with the result that the other annular surface provides a raceway, wherein the raceway has a spherical contour, and the bore center axis of each bore in the bearing ring and in the sealing disc has an engaged profile which converges onto the cylindrical contour of the one annular surface.

A bearing housing for use in a wind turbine is provided. Further, the bearing housing is axially coupled to a base support structure using plurality of fastening points on the bearing housing. The bearing housing may be coupled to the base support structure at multiple points so that the load is distributed evenly to the support structures such as base plate and the tower. The bearing housing is coupled to the base support structure using a fastener. The horizontal central axis of the bearing housing coincides with the horizontal central axis of the base support structure.

A bearing system is provided, configured to surround a rotor along a circumferential direction corresponding to the rotor. The rotor is extended along an axial direction co-directional to a centerline axis of the rotor. The bearing system includes a body from which a plurality of first support members is each extended, and wherein the plurality of first support members is spaced apart from one another along the circumferential direction. Each first support member includes a first axial support arm extended along the axial direction and a first radial support arm extended from the first axial support arm along a radial direction. The first radial support arm is configured to position a bearing element in contact with a bearing surface at the rotor.

A split double row spherical roller bearing comprising an outer ring including an outer race, an inner ring within the outer ring including an inner race, a cage mounted between the inner and outer races, the cage mounting rollers which engage the inner and outer races, the inner ring, inner race, outer ring, outer race, and cage each comprising two generally semicircular parts engageable together to form a circular component via respective radially extending contact surfaces, and characterized in that the contact surfaces of at least the outer ring comprise a saw-tooth arrangement in which the angle of each saw tooth joint is between 25 and 40 degrees.

A flanged bearing outer ring unit includes an outer ring formed from metal and having a sliding interface and a polymeric flange attached to the sliding interface by overmolding and/or injection molding, and, optionally including an embedded metal or organo-sheet reinforcement. Also a method and a molding form for forming the flanged bearing outer ring unit.

Provided is a double-row self-aligning roller bearing including: an inner ring; an outer ring having a spherical raceway surface; and rollers arranged in two rows and interposed between the inner ring and the outer ring, wherein a ratio of a contact angle θ1 in one row to a contact angle θ2 in the other row falls within a range of 0.25≤θ1/θ2≤0.5, and a ratio of distance B1 in a bearing width direction from an end face of the bearing on a side of the one of the rows to an intersection of two lines of action defining the contact angles of the two rows, relative to a distance B2 in the bearing width direction from an end face of the bearing on a side of the other of the rows to the intersection falls within a range of 0.5≤B1/B2≤0.6.

A bearing flange for a drive system of a hand-held power tool includes a first bearing point for a driveshaft of a drive motor, a second bearing point for an intermediate shaft, and a third bearing point for a hammer tube. At least one bearing point includes a ball bearing, which is received in a receiving opening of the bearing flange and is axially secured therein by a snap ring.

A bearing assembly may include an integral sensor module retained within a bore in the bearing housing. The sensor module includes at least one strain gauge oriented to sense a compressive load acting on the bearing housing. The sensor module may be retained within the bore under an axial compressive load. The sensor module may include a power source and a wired or wireless communications module for transmitting information indicative of the compressive load to an external instrument or other system.
