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.

A solar tracker bearing apparatus mountable to an upright support post for rotatably supporting a torque tube beam of a solar tracker assembly and including: a rotatable bearing assembly supported for rotation about an axis of rotation by a stationary saddle assembly. The rotatable bearing assembly includes a central portion and first and second spaced apart arcuate peripheral portions, the central portion defining a beam slot, the first arcuate peripheral portion including a first arcuate rim bearing and the second arcuate peripheral portion including a second arcuate rim bearing, and the first and second rim bearings being spaced apart in a direction parallel to the axis of rotation of the rotatable bearing assembly. The stationary saddle assembly includes a first arcuate bearing race slidably supporting the first arcuate rim bearing and a spaced apart second arcuate bearing race slidably supporting the second arcuate rim bearing.

A rotor support system for a gas turbine engine includes a rotatable drum rotor and a non-rotatable support casing. The rotor support system includes a bearing assembly configured for positioning between the rotatable drum rotor and the non-rotatable support casing. The bearing assembly includes, at least, a stationary support frame and a rotatable race. Further, the rotatable race is configured to engage the rotatable drum rotor at separate and discrete locations that are circumferentially spaced apart around the rotatable drum rotor.

Among other things, a radiation system is provided. The radiation system includes a stationary unit and a rotating unit that rotates about an axis relative to the stationary unit. A radiation source and a detector array are mounted to the rotating unit. A wheel mechanism at least partially supports the rotating unit and facilitates rotation of the rotating unit relative to the stationary unit. A lift unit is supported by the stationary unit and engages the rotating unit. When the lift unit is in a lowered position, the rotating unit is supported by the wheel mechanism and the lift unit is spaced a distance apart from the rotating unit. When the lift unit is in a raised position, the rotating unit is supported by the lift unit and the rotating unit is spaced a second distance apart from the wheel mechanism.

In a motor assembly, a rotor and a trigger wheel are each secured to a first race of a four-point contact ball bearing. The circumferential position of the rotor and trigger wheel are each fixed with respect to the first bearing, and therefore with respect to one another. A resolver sensor is bolted to a housing. A second race is mounted at a fixed axial position relative to the housing, thereby locating the trigger wheel with respect to the resolver sensor. In some embodiments, the first race may be an inner race and the second race an outer race. In other embodiments, the first race may be an outer race and the second race an inner race.
