A bearing assembly comprising: (a) an inner journal for supporting a shaft and having a frusto-conical contact surface facing radially outwardly; (b) an outer journal surrounding at least part of the inner journal and having a frusto-conical contact surface which faces radially inwardly; and (c) an adjustment feature for adjusting the axial location of the inner journal relative to the outer journal.

A linking device has a bearing and is suitable for use with a weapons system. The device provides adjustable rotational resisting torque of two coaxial cylindrical parts which are rotatable relative to one another about a shared axis. The bearing includes two rings made of a resiliently deformable material and is capable of respectively engaging with the two cylindrical portions, and between which rolling elements are arranged such as to be in contact with raceways of said rings. The device further includes a controllable member for adjusting the tightening of the rings, wherein the controllable member is capable of engaging one of said parts in order to engage with said bearing.

A bearing assembly (12) for a rotating element (13) has one race (15) adapted to be fixed relative to ground (11) and to selectively be free for arcuate movement relative to ground. A selective locking device (18) can be provided for the relatively fixed/movable race (15).

Examples of the disclosed technology provide actuator locking systems and methods with enhanced reliability. The disclosed systems and methods facilitate a compact design that can improve safety and machine life for machines that implement them. Moreover, the systems and methods can be utilized in various types of machines, including spacecraft, aircraft, and other machines that adapt to different structural configurations for different operational scenarios (including different operational environments). To achieve a compact, reliable design, examples utilize a series of specially designed cuffs arranged along a shaft. Namely, an actuator locking system of the presently disclosed technology may comprise: (1) a primary link cuff; (2) a secondary link cuff; and (3) a drive link cuff. The cuffs can be arranged along a shaft with the secondary link cuff positioned between the primary link cuff and the drive link cuff.

A bearing unit (10) has a radially outer ring (31), a radially inner ring (33), an eccentric locking collar (40), a row of rolling bodies (32), and a sealing device (50). The sealing device (50) is arranged on the same side as the locking collar (40) and is interposed between the radially inner ring (33), the radially outer ring (31) and the locking collar (40). The sealing device (50) includes a metal shield (55) stably connected to the radially outer ring (31), and an elastomeric component (60) co-molded on the shield (55) in a radially inward direction. The elastomeric component (60) has a plurality of lips, of which at least one lip (64, 65) is in contact with the locking collar (40).

A bearing block adapted for use in a gear pump assembly. The bearing block includes a bearing surface configured to face one or more gears. The bearing block further includes a bearing block body formed with a recess. The bearing block further includes an insert located within the recess. The insert includes an insert body including an outer surface. The insert body has a tapered shape that tapers outwardly from the bearing surface. The insert further includes a plurality of ridges disposed on the outer surface. The plurality of ridges defines one or more grooves therebetween. The recess includes a tapered shape complementary to the tapered shape of the insert body, such that the insert body engages with the bearing block body.

An expansion sleeve for a connection device, the sleeve arranged on an axle of the connection device to secure the axle in a hole, the sleeve comprising: a first section with a first outer diameter; and a second section with a second outer diameter, the first section has a conical shape with a tapering inner wall configured to abut a tapered section of the axle, and an outer wall configured to abut an inner wall of the hole, the second section to axially abut a fastening device arranged at an end of the axle, the second outer diameter of the second section is smaller than the first outer diameter of the first section, and the second section comprises an inner wall extending with an angle relative the axial direction of the sleeve which is smaller than the angle of the tapering inner wall of the first section.

A bearing unit configured to be clamped on a machine shaft includes a stationary radially outer ring, a rotatable radially inner ring having a radially inner surface, a row of rolling bodies interposed between the radially outer ring and the radially inner ring, and a clamping device that includes a clamping sleeve between the radially inner ring and the machine shaft, the clamping sleeve including a threaded flange portion and a circumferential slit configured to deform and tighten around the machine shaft, and a ring nut to screw onto the threaded flange portion and exert an axial force on the radially inner ring, the radially inner surface of the radially inner ring engages the radially outer surface of the clamping sleeve.

A bearing including an inner ring, an outer ring, and a plurality of rolling elements arranged between the inner ring and the outer ring, the inner ring including an annular portion and an extension portion protruding in an axial direction from an end surface of the annular portion on a radially inner side and having a slit formed in the axial direction; and a clamping member that is externally fitted to the extension portion, and is configured to clamp and fix the extension portion to a shaft. A radially inner end portion of the clamping member on a bearing side is provided with a stepped portion to which a radially outer end portion of the annular portion is allowed to be fitted.
