An inner ring assembly for a bearing includes a bearing annular body disposable about the shaft and having a bearing inner race and a plurality of slotted openings defining a plurality of arcuate mounting tabs, the slotted openings each having a curved inner end and each tab including a substantial recess to reduce stress concentration. An annular locking collar is disposed about and clamps the mounting tabs against the outer surface of the shaft to retain the inner ring. The collar is retained on the ring body by a retainer projection(s) extending outwardly from the mounting tabs and engaging with the collar or a retainer member projecting inwardly from the collar and engaging with one of the mounting tabs. The collar has a gap and a flat outer surface section spaced from the gap to increase the dynamic balance and the flexibility of the collar.

A bearing, including: an inner ring defining a first groove; an outer ring including a radially inner surface, the radially inner surface facing an axis of rotation of the bearing and defining a second groove and a third groove; a cage radially disposed between the inner ring and the outer ring; a plurality of balls retained by the cage, and disposed in the first groove, and in the second groove; and a preloaded resilient washer assembly including a rigid washer and a resilient washer including a radially outermost surface disposed in the third groove. The resilient washer urges the rigid washer away from the outer ring in an axial direction parallel to an axis of rotation of the bearing.

A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

A non-locating bearing assembly includes a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a first stationary bearing ring and a second rotatable bearing ring. The rotatable bearing ring is fixedly connectable to the rotatable component, and a bearing carrier is attached to the stationary bearing ring in a rotationally fixed but axially displaceable manner by a combination of a friction fit and an interference fit. The bearing carrier is configured to be fixedly connected to the stationary component.

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.

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 mobile milling machine includes a cutting rotor disposed along a rotor drum delineating a drum rotation axis and accommodated in a rotor chamber delineated by chamber enclosure. To rotatably support the rotor drum with respect to the chamber enclosure, the rotor drum can include a bearing end and the chamber enclosure can include a bearing bore that are adapted to form a drum bearing assembly. The drum bearing assembly may include a bearing hub and a bushing configured to make a sliding frictional contact along complementary taper surfaces. The floating bushing may be floatingly retained in a chamber door of the chamber enclosure.

The bearing provides a first ring and a second ring centered on an axis, each of the first and second rings being provided with an outer cylindrical surface, with an inner cylindrical surface, and with lateral faces that axially delimit the outer and inner cylindrical surface. One of the inner and outer cylindrical surfaces and/or one of the lateral faces of the first ring includes a textured area provided with a groove extending circumferentially and with two protrusions disposed one on each side of the groove and extending along the groove.

A bearing unit having a stationary radially outer ring; a radially inner ring rotatable around a central rotation axis (X) of the bearing unit and provided with at least one raceway and, in a terminal portion thereof, with at least one through hole; at least one row of rolling elements interposed between the radially outer ring and the radially inner ring; and at least one clamping element, which is accommodated in the through hole, to lock the radially inner ring on to a rotating shaft. A first radially outer cylindrical surface of the terminal portion of the radially inner ring has a diameter smaller than the diameter of a second radially outer cylindrical surface of a second terminal portion of the radially inner ring.
