An assembly is described for reducing the moment from a deflected shaft. A shaft includes a shaft body and an outer shaft surface. A bearing includes an inner race engaging the shaft, the inner race including an inner race surface and a race body with axial edges. When the shaft body or a portion of the bearing is deflected from a nominal axis of relative rotation, the shaft body applies a force to the bearing at an axially outermost location that is axially inward from at least one of the axial edges of the race body. Accordingly, an effective line of action of the force is applied at a location that is axially removed from the at least one of the axial edges of the race body towards a central plane of the bearing.

A roller of a support arrangement for a rotary milking platform, where the support arrangement includes a first rail member fixedly connected to the rotary platform, a second rail member stationarily arranged in a position below the platform, and a plurality of rollers arranged in a vertical space between the first rail member and the second rail member. Each roller includes a peripheral surface comprising a contact surface to be in contact with a contact portion of the first rail member and a contact portion of the second rail member. The peripheral surface of the roller includes two beveled surfaces arranged at opposite sides of the contact surface which are located at a smaller distance from a rotary axis of the roller than the contact surface.

A bearing system for a compressor including an unloader at least partially received within a recess of a driveshaft. The unloader includes an outer surface that is engaged with a bearing. An inner surface of the unloader is curved such that the unloader is pivotable relative to the driveshaft unload forces on bearing caused by deflection of the driveshaft.

A cylindrical roller bearing includes at least one outer ring with a raceway, an inner ring with a raceway, and a plurality of cylindrical roller elements rollable along the raceways of the inner ring and the outer ring. The raceway of the inner ring has an at least partly crowned profile, the crowned profile having a crowning radius R and is formed such that: 25 L.sup.2/D<R<55 L.sup.2/D, in which L is the length of each one of the cylindrical roller elements and D is the diameter of each one of the cylindrical roller elements.
