The present disclosure discloses a polymer joining ring for a bearing assembly and is configured to retain a first inner ring and a second inner ring together to the bearing assembly. The polymer joining ring includes an outer surface and an inner surface. The outer surface includes a W or E shaped geometry throughout and includes a pair of flanges extending radially outwards at corners from outer surface, and a semi-circular protrusion extending at middle of the polymer joining ring. The pair of flanges are placed in tapered narrow grooves of the first inner ring and the second inner ring, and the semi-circular protrusion is placed in a triangular shape space produced between the first inner ring and the second inner ring can be tightly connected to each other. The joining ring is made of a polymer material that facilitates ease in assembling and accurate positioning of the inner rings.

A bearing assembly for a drivetrain of a wind turbine includes at least one shaft having a circumferential outer surface and a bearing secured circumferentially around the circumferential outer surface of the shaft(s). Further, the bearing assembly includes an elastomer support arranged on at least one of an inner surface or an outer surface of the bearing. The elastomer support is constructed, at least in part, of an elastomeric material.

A seal assembly is for sealing a space adjacent to a bearing and defined between an inner member and an outer member disposed about the inner member. The seal assembly includes an annular seal disposed about the inner member and having a sealing lip sealingly engageable with the inner member. An annular load ring is disposed within the outer member bore and has an inner circumferential surface defining a bore, the seal being disposed within the bore and coupled with the ring. A first axial end of the ring is disposed against the bearing outer ring, or a spacer disposed axially between the load ring and the bearing outer ring, and a second axial end is disposed against a radial surface of the outer member. The load ring is configured to support axial loading on, and to prevent axial displacement of, the bearing outer ring.

A follower bearing includes an outer ring, rolling elements, and a cage retaining the rolling elements. The outer ring includes an annular first member made of steel, and an annular second member made of resin and covering an outer circumferential surface of the first member. The first member includes a tubular portion. The second member includes a first portion disposed on one side of the tubular portion in an axial direction and having a first opposing surface that opposes an outer circumferential surface of the cage in a radial direction, and a second portion disposed on the other side of the tubular portion in the axial direction and having a second opposing surface that opposes the outer circumferential surface of the cage in the radial direction. In the radial direction, the first and second opposing surfaces are each disposed on a more outer circumference side than a second raceway surface.

A seal assembly is for sealing a space adjacent to a bearing and defined between an inner member and an outer member disposed about the inner member. The seal assembly includes an annular seal disposed about the inner member and having a sealing lip sealingly engageable with the inner member. An annular load ring is disposed within the outer member bore and has an inner circumferential surface defining a bore, the seal being disposed within the bore and coupled with the ring. A first axial end of the ring is disposed against the bearing outer ring, or a spacer disposed axially between the load ring and the bearing outer ring, and a second axial end is disposed against a radial surface of the outer member. The load ring is configured to support axial loading on, and to prevent axial displacement of, the bearing outer ring.

A hybrid bearing assembly includes a bushing. A sleeve is rotationally disposed within the bushing and a support layer is disposed around an outer perimeter of the bushing. A protective sleeve is disposed abutting the sleeve. A protective bushing is disposed abutting the bushing.

A charging roll includes a core member, a rubber base material disposed around the core member, and a surface layer disposed around the rubber base material. The ten point height of irregularities R.sub.Z of a surface of the surface layer is equal to or greater than 3.9 micrometers, and is equal to or less than 6.1 micrometers. The mean spacing between peaks S.sub.m of the surface of the surface layer is equal to or greater than 12.5 micrometers and is equal to or less than 13.5 micrometers.

Disclosed is a paper-sheet-feeding/conveying roller having a shaft, and a bi-layer roller material which is formed of an inner layer provided on the shaft and an outer layer. The inner layer provided on the shaft is a foamed elastic layer. The outer layer provided on the foamed elastic layer is a non-foamed elastic layer. The foamed elastic layer is formed of a foamed elastic body of silicone-modified EPDM.

A fluid bearing for a wind turbine including a bearing housing, a plurality of bearing pads inside the bearing housing and circumferentially distributed around a longitudinal axis of the fluid bearing, a plurality of supporting structures, each supporting structure having at least a first interface detachably connected to a respective seat provided in the bearing housing and at least a second interface detachably connected to a respective bearing pad of the plurality of bearing pads, the supporting structure including an elastomer allowing tilting of the respective bearing pad parallel to the longitudinal axis, the elastomer being interposed between the respective seat and the respective bearing pad is provided.

A slewing bearing includes first and second rings and rolling elements therebetween. The first ring has a shoulder, and a cap is fixed to the first ring that, with the shoulder, defines a radially outwardly facing circumferential groove. A sealing contact member is fixed to a surface of the second ring. A first seal is mounted in the groove, and a sealing member is mounted on the cap. The first seal and the sealing member each include a sealing lip in sliding frictional contact with the sealing contact member.
