A slotted tube shaft carrying a blade head of a blade twister rotates in a slotted, stationary bearing housing for an endless band-shaped cutting or sawing element supported by two axially spaced subassemblies each having C-shaped, axially spaced, and slotted inner and outer bearing washers radially between the slotted stationary bearing housing and the slotted tube shaft. The inner and outer washers are fixed in the stationary bearing housing against rotation relative thereto with slots of the stationary bearing housing and washers radially aligned with one another. Respective sets of at least three roller bearings centered on and angularly distributed about the axis and fixed against angular movement between each of the inner washers and the respective outer washer. Each roller bearing radially outwardly engages the slotted stationary bearing housing and radially inwardly engages the tube shaft.

The invention relates to a device for receiving workpieces to be balanced in a machine for performing an unbalance compensation having a bearing device (2) arranged on a machine frame for rotatable mounting of the workpiece (3) around a bearing axis (L), wherein the bearing device (2) has at least one bearing block (10) having two bearing shells (18, 19) differing in diameter and lying adjacent to each other in a direction transverse to the bearing axis (L). The bearing block (10) is movable transversely to the bearing axis (L) of the bearing device (2) into two bearing positions and another one of the two bearing shells (18, 19) is aligned centrally to the bearing axis (L) in each of the two bearing positions.

An arrangement for supporting a rotary drum, the rotary drum having at least three riding rings distributedly arranged along the axial direction of the rotary drum, the arrangement including a pair of relatively spaced rollers for supporting a riding ring, at least one bearing for each roller, a support for each bearing mounted for movement of the roller toward and away from the shell of the rotary drum and a spring system exerting a spring force acting on the support to counteract the weight of the rotary drum resting on the rollers, wherein the spring system includes a pressure vessel charged with a compressed gas that exerts the spring force and the rotary drum includes at least three riding rings and only at least one middle ring arranged between two outer rings is supported by a pair of relatively spaced rollers that are equipped with the spring system.

A method and a system for operating a rotary vessel, rotated by a tire riding on trunnions, which monitors the position of the tire relative to the upper and lower thrust bearings and the temperature of the upper and lower thrust bearings and provides an output that alerts an operator when corrective action should be taken.

A support assembly for a telescopic conveyor may be provided. The assembly may include at least two spaced apart bearings and a reservoir of hydraulic fluid, the bearings being coupled to the reservoir to impart force to and receive force from the hydraulic fluid. The reservoir may be configured to transmit force received from any one of the bearings to at least one other of the bearings by the hydraulic fluid. The assembly can distribute uneven loads amongst the bearings thereby maintaining contact between the bearings and the conveyor, and reducing wear on the bearings and associated components.

An end member (30) comprises: a tubular bearing member (40); and a shaft member (50), wherein the shaft member comprises: a shaft-like rotating shaft (51) which is disposed coaxially to the bearing member, and moves in the shaft line direction by rotating around a shaft line with respect to the bearing member; and a tip end member (55) which is disposed coaxially to the rotating shaft, and where a rotating force receiving member (58) provided with an engaging member (60) which engages with a driving shaft (70) of the image forming apparatus main body is disposed at a tip end, wherein a rotating force around the shaft line is transmitted to the rotating force receiving member, the rotating shaft, and the bearing member, in this order, and the rotating force receiving member moves to be inclined with respect to the shaft line.

An apparatus for rotatably supporting a rotating cylindrical body. The apparatus comprises a pair of roller assemblies for supporting an annular bearing surface of a rotating cylindrical body. Each of the roller assemblies comprises a cylindrical roller having a circumferential bearing surface in supporting engagement with the annular bearing surface of the rotating body; first and second shaft extensions extending from the roller; bearings for rotatably supporting the first and second shaft extensions; and a pivot plate for supporting the bearings, the pivot plate being pivotally attached to a base by a pivot pin such that the cylindrical roller self-adjusts to the annular bearing surface of the rotating body.
