A sealing arrangement includes a housing, a shaft and a sealing unit. The sealing unit includes a sealing ring having a retaining section and having a sealing lip which extends outwardly from the retaining section in a direction radial to the central axis of the sealing unit and which dynamically sealingly rests against a sealing surface of a housing of the sealing arrangement. The sealing unit includes an internally tensioning clamping ring which is arranged embedded in the material of the sealing ring and secures the axial position of the retaining section in the retaining groove and ensures that the retaining section is circumferentially pretensioned and statically sealingly rests against the shaft.

A track roller assembly includes a wheel body, a bearing, a wheel axle, a cap element, a rotating oil seal, an end cover and an oil body. The wheel body has a thread. The bearing is disposed on the wheel body. The wheel axle is disposed through the bearing. The cap element has a screw corresponding to the thread. One side of the rotating oil seal is connected to the cap element, and another side of the rotating oil seal rotatably abuts the wheel axle. The end cover is connected to the wheel axle. The oil body is limited to an accommodating space formed by the wheel body, the wheel axle, the cap element and the rotating oil seal.

A Pulley device for a tensioning or winding roller for a transmission element including a pulley, and a rolling bearing provided with a rotating outer ring, the pulley being mounted on an outer surface of the outer ring, a fixed inner ring, the rings being coaxial and forming a radial space between them, and at least one row of rolling elements arranged in the radial space. The pulley device further includes at least one annular protection flange with a radial body. The flange is fixed to the rotating outer ring by crimping an axially protruding portion of the pulley towards an outer edge of the flange.

A dry-lubricating apparatus, for press fitting onto a mating part, includes (a) a frame, (b) a rubber gasket fixed to the frame to create an interference with a mating surface of the mating part so as to enable the press fitting, and (c) a lead-in edge fixed to at least one of the frame and the rubber gasket. The lead-in edge includes a dry lubricant such that, when the dry-lubricating apparatus is slid onto the mating part, along the mating surface and with the rubber gasket trailing the lead-in edge, a portion of the dry lubricant is abraded off the lead-in edge to reduce friction between the rubber gasket and the mating surface.

A bearing providing a first ring assembly and a second ring assembly, the first ring assembly including at least a first ring and an outer cap reversibly fixed to first ring. The bearing further providing at least one sealing element mounted radially into a cylindrical surface of the first ring assembly and provided with a sealing lip in sliding frictional contact with the second ring assembly. The bearing including at least one adjusting shim mounted radially between the first and second ring assemblies, the adjusting shim being axially located between the outer cap of the first ring assembly and the sealing element; or between the first ring of the first ring assembly and the sealing element.

Conveyor idler monitoring apparatus, systems and methods are provided. In some embodiments, one or more sensors (e.g., temperature sensors, load sensors, etc.) are supported by the shaft of a conveyor idler. In some embodiments, one or more sensors are in data communication with a wireless transmitter. In some embodiments, a power generator driven by rotation of the idler is in electrical communication with one or more sensors and/or a wireless transmitter. In some embodiments, a plurality of idlers monitoring systems are in data communication with a conveyor monitoring system and/or operational monitoring system.

A rolling bearing has an inner and an outer bearing ring. Each bearing ring has an inner and an outer shell surface. The roller bearing has rolling elements, which roll on raceways provided on the respective shell surfaces of the bearing rings, and a sealing disc connected to one of the bearing rings and operatively connected in a sealing manner to the other bearing ring. To connect the sealing disc to the bearing ring, one of the shell surfaces of the one bearing ring includes a first connecting means and the sealing disc includes a second connecting means. The first connecting means provide a rotating engagement in which the second connecting means engage in a connected state of the bearing ring and the sealing disc.

There is provided a wheel bearing sealing arrangement for a wheel bearing of a vehicle, comprising an outboard bearing having an outboard periphery intended to face away from a central longitudinal axis of the vehicle and an inboard periphery intended to face towards the central longitudinal axis of the vehicle, wherein the outboard bearing comprises a first race-forming part and a second race-forming part which surrounds the first race-forming part; an outboard seal arranged between the first race-forming part and an opposite part; and a safety washer pressed against the outboard periphery of the first race-forming part, wherein the outboard seal comprises a sealing part pressed against and in direct contact with the safety washer. There is also provided a vehicle comprising such a wheel bearing sealing arrangement.

A bearing unit may have a radially outer ring, a radially inner ring, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, a casing inside which the rings of the bearing unit are housed. The bearing unit may further have a sealing device and a disc-like element for protecting the sealing device, made as one piece, entirely of plastic or composite material, axially external with respect to the sealing device, stably anchored in a seat of the casing and having a radial distance (d2) between a radially internal surface of the disc-like element and the radially inner ring ranging between 0.75 mm and 0.95 mm so as to block large-size external contaminants, without making contact with the radially inner ring.

A seal ring (26) configured to be employed with a cross shaft (16) including a center section (17) and four shaft sections (18a, 18b, 18c, 18d) extending in four directions from the center section and formed with step faces (17a) where the center section widens out from base ends of the shaft sections outward in radial directions of the shaft sections, and with bearings (21) for mounting to leading end portions of the shaft sections. The seal ring is fitted over the shaft section and interposed between the bearing and the step face. The seal ring includes a seal lip (34) configured to contact the step face around the entire circumference, and an indentation (36) the seal lip enters by deforming when mounted to the cross shaft.
