A solar tracker bearing assembly has a rotating element sandwiched between two mounting brackets and held together by fasteners. The rotating element includes an arc-shaped slot such that the rotating element can pivot against the fixed mounting brackets. Bearings may be positioned within the arc-shaped slot. The rotating element can be configured to accept toque tubes of various cross-sections.

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.

A method and an equipment permitting to optimally handle and support a roll made of at least an inert material and transfer the torque from a bearing to a roll or the other way around without damaging them, the roll and bearing being immersed in molten metal.

A double-row one-way bearing includes a bearing outer ring and a bearing inner ring coaxially arranged around a central axis. Spherical rollers are arranged between the bearing outer ring and the bearing inner ring. Wedges are radially arranged between the bearing outer ring and the bearing inner ring relative to the central axis, and spaced apart from the spherical rollers in the axial direction. Each wedge is provided with a groove at the side away from the bearing inner ring. A cage is coaxially arranged with the bearing outer ring and the bearing inner ring and provided with roller holding portions and wedge holding portions. The spherical rollers are respectively held in the roller holding portions and the wedges are respectively held in the wedge holding portions. An elastic limit ring passes through the groove of each wedge to apply a radially inward force to each wedge.

A bearing block assembly for supporting a calender roll having a housing including a preload access port, a base surface, and a first side and a second side. A first contact surface on the first side extends from the base surface at a first angle, and a second contact surface on the second side extends from the base surface at a second angle. Within the housing is a first bearing block having a first bearing block surface and a first bearing bore, a second bearing block having a second bearing block surface and a second bearing bore, and a third bearing block having a preload surface and a third bearing bore. The first bearing block surface is disposed over the first contact surface, the second bearing block surface is disposed over the second contact surface, and the preload surface is positioned between the preload access port and the base surface.
