An idler roller having a fixed shaft with at least one spherical bearing and a second bearing which may, but need not be, a spherical bearing. In some embodiments, the second bearing is slidably-mounted on a central shaft. A shell is mounted between these bearings. Any changes in dimensions resulting from changes in temperature may them be accommodated by sliding movement of the second bearing, sparing the shell from distortion by bending or buckling. In other exemplary embodiments, the spherical bearing includes a first housing element fixedly-mounted on a central shaft and a complementary first free element disposed against the first housing element. A second bearing element is mounted on the central shaft, and a shell is attached to the first free element and rotatably-mounted to a second bearing element with a biasing element mounted on the central shaft urging a second free element away from the first free element.

A system for lubrication of a bearing of a crop transport and/or processing system of a harvesting machine includes a supply container for storing a lubricant, a delivery pump and a lubricant line for delivering the lubricant from the supply container to the bearing, and a drainage channel and a suction pump for returning the lubricant from the bearing to the supply container.

A planetary gear system is provided in one example embodiment and may include a planet gear further comprising a bearing system, the bearing system further comprising an inner bearing assembly comprising a spherical bearing and an outer race; an outer bearing assembly comprising a plurality of cylindrical roller bearings, an inner race, and an outer race; and a race element comprising an inner surface and an outer surface, wherein the outer surface of the race element is the inner race for the outer bearing assembly and the inner surface of the race element is associated with the outer race for the inner bearing assembly.

A spherical bearing for a damper system includes a first segment and a second segment with a ball therebetween. The ball includes a shaft extending therefrom. The shaft extends out of the first segment. A lubricious liner is disposed between the first segment and the second segment.

A housing element having a casing provided with a cylindrical seat, a bearing unit located inside the cylindrical seat of the casing, a metal ring arranged between the casing and the bearing unit and provided with a spherical seat. The metal ring is assembled inside the cylindrical seat of the casing and is axially movable along the cylindrical seat. The bearing unit is coupled with the metal ring by its spherical seat and is axially movable together with the metal ring. The metal ring is provided with a first groove, which is radially external, and a first radial hole in fluid communication with the first groove so as to allow a supply of grease to the bearing unit.

A support assembly for movable, rotating or sliding shafts, having a bearing unit having an inner ring, an outer ring, and a row of rolling bodies interposed between the inner and outer rings, a casing, a cover for fluid sealing an opening of an internal seat of the casing, a rear sealing device on a side opposite the cover having a metal screen and a vulcanized rubber liner equipped with an axially outer first sealing lip and with an axially inner second sealing lip, an axially inner sealing device, having a first shield provided with a vulcanized rubber liner having a plurality of sealing lips, the outer ring having a step extending axially inward and provided with a second shield having a vulcanized rubber liner with a plurality of sealing lips.

A bearing unit having a radially outer ring which is stationary, a radially inner ring, rotatable around a central rotation axis (X) of the bearing unit, provided, in an end portion thereof, with at least two segments of circular sectors separated by at least two grooves, a row of rolling elements interposed between the radially outer ring and the radially inner ring, and a collar for clamping the radially inner ring on to a shaft; each circular sector segment is provided with a lip having a thickness (s) and a step having a thickness (s+s1), wherein the thickness (s+s1) of the step is greater than the thickness (s) of the lip.

A housing element having a casing provided with a spherical seat, a bearing unit located inside the spherical seat of the casing and provided with a radially inner ring, and a plastic end cover provided with a radial through-hole so that a machine shaft can be inserted inside it, the end cover being integral with the shaft and rotatable with the shaft, and the end cover being provided with an elastomeric seal for forming a static seal on the shaft.

A retention system for a bearing member includes a sleeve member and a retention member. The retention system includes an inner shoulder adapted to limit movement of the bearing member in at least one of a first axial direction and a second axial direction relative to the bore. The retention system includes an outer shoulder adapted to limit movement of at least one of the sleeve member and the retention member in at least one of the first axial direction and the second axial direction relative to the bore. The retention system includes a plurality of fasteners adapted to limit movement of each of the sleeve member and the retention member in at least one of the first axial direction and the second axial direction relative to the bore. Each of the sleeve member and the retention member is adapted to limit contact of the bearing member with the bore.
