A bottom wall of the annular groove includes a plurality of depressions alternating with a plurality of projections.

A bearing unit comprising a radially outer ring having a radially outer spherical surface with a convex shape, a radially inner ring mounted on a rotating or oscillating shaft, and a plurality of rolling bodies interposed between the radially outer ring and the radially inner ring to allow the relative rotation of the radially inner ring and outer ring; a locking system for locking the bearing unit being provided with two threaded through holes that are made through the radially inner ring from opposite sides with respect to the radially outer ring and to the plurality of rolling bodies, and, for each threaded through hole with a respective grub screw locking the radially inner ring on the shaft.

A forage harvester that includes a cutterhead assembly and two frame parts between which the cutterhead assembly is rotatably suspended. The forage harvester assembly is held on both frame parts by a clamp bearing that defines a rotary axis. Contact points between an element on the frame part side and an element on the assembly side of the clamp bearing lie on a spherical surface centered on the rotary axis.

An electromechanical servo steering system with an electric servomotor having a motor shaft that drives a shaft which cogs with a helical gear. The shaft is arranged in a transmission housing and is mounted rotatably about an axis of rotation at its end near the motor in a bearing arrangement and is mounted pivotably in the transmission housing about a pivot axis which lies transverse to the axis of rotation. At least one spring element is provided which axial pretensions a bearing element that is pivotably movable with the shaft about the pivot axis, of the bearing arrangement in a spring-elastic manner against a bearing element that is arranged in a stationary manner in the transmission housing, of the bearing arrangement, wherein precisely two spring elements are provided which are arranged oppositely in the circumferential direction of the bearing arrangement.

An outer ring for a bearing includes an outer sleeve that defines a first exterior surface and a first interior area. The first interior area is defined by a first inner surface. The first inner surface has a first fastener mechanism formed therein. The outer ring includes an inner sleeve that defines a second exterior surface and a second interior area. The second interior area is defined by a second inner surface. The second exterior surface has a second fastener mechanism formed therein. The inner sleeve is removably disposed in the first interior area by selective engagement of the first fastener mechanism with the second fastener mechanism. The outer sleeve surrounds the inner sleeve and extends axially from a first end to a second end thereof. The inner sleeve extends from the first end to the second end of the outer sleeve.

Casing of a bearing unit for food applications, made of polymeric material and provided internally with a spherical seat for housing the bearing unit, the casing having a reinforcement in the form of a metal ring co-molded inside the casing and accommodated around the spherical seat of the casing.

A support assembly having a central axis (X) includes a casing made of a composite material and including a radially internal mounting surface, a bearing unit provided with a radially outer ring having a radially external, spherical mounting surface, and a metal insert interposed between the casing and the bearing unit and housed inside the radially internal mounting surface of the casing. The metal insert includes a radially internal, spherical mounting surface, and the bearing unit is mounted to the radially internal, spherical mounting surface of the metal insert.

A bearing unit comprising a stationary radially outer ring with a spherical radially outer surface with a convex shape, a radially inner ring that is rotary about a central rotation axis (X) of the bearing unit and is mounted on a rotating or oscillating shaft. A diametrical through-hole is formed in a first cylindrical portion that is used to receive an elastic element for locking the radially inner ring on the shaft, a plurality of rolling bodies interposed between the radially outer ring and the radially inner ring to enable the relative rotation of the two rings, and a locking element locking the radially inner ring on the shaft. The radially inner ring is provided with two threaded through-holes from opposite sides with respect to the radially outer ring and to the rolling bodies, for housing respective grub screws for locking the radially inner ring on the shaft.
