Abstract: A bearing assembly includes an inner ring having an inner raceway and an outer ring disposed about the inner ring and having an outer raceway. A plurality of rolling elements, preferably balls, are disposed between the inner ring and the outer ring such that each one of the rolling elements rolls simultaneously upon the inner raceway and the outer raceway. The inner ring and/or the outer ring is formed of a lightweight composite material, the composite material including a mixture of a base polymer, reinforcing fibers and a lubricant, preferably polyoxymethylene, glass fibers and silicone. Further, each one of the inner raceway and the outer raceway is formed such that each ball contacts two separate points on the inner raceway and contacts two separate points on the outer raceway such that the bearing assembly is configured to support loading in both directions along a central axis.

Abstract: A thin section bearing assembly is for a gantry assembly and includes inner and outer rings each having inner and outer circumferential surfaces and rolling elements grooves and are each sized such that a ratio of the inside diameter to radial thickness is at least thirty (30). A plurality of rolling elements, preferably balls, are disposed between the outer ring groove and the inner ring groove. At least one elastomeric annular damper is disposed between the outer ring and the housing and/or between the inner ring and the rotor and has first and second axially spaced sections. As such, the first section is compressed more than the second section under bending moments in a first angular direction and the second section is compressed more than the first section under moments in a second angular direction. The one or more annular dampers each have a thickness calculated to optimize vibration reduction.

Abstract: A rolling bearing is disclosed which comprises an outer ring and an inner ring, wherein rolling elements are arranged between the outer ring and the inner ring, and wherein the rolling elements are spaced apart by a cage being arranged between the outer ring and the inner ring, wherein the cage is made of polymer containing reinforcing fibers, and the outer ring and/or the inner ring are steel rings with fine carbide precipitation.

Abstract: A rolling-element bearing cage or a rolling-element bearing cage segment includes a first side ring or a first side ring segment formed from aluminum alloy AA2618, a second side ring or a second side ring segment formed from aluminum alloy AA2618, and at least one bridge formed from aluminum alloy AA2618, the at least one bridge connecting the first side ring to the second side ring or connecting the first side ring segment to the second side ring segment.
