A separator for a ball bearing includes an annular body having a centerline, opposing first and second axial ends and an inner circumferential surface defining a central pocket sized to receive one of the plurality of balls. Preferably, the annular body has a concave outer circumferential surface defining an annular channel and configured to contact at least one adjacent one of the balls along a curved line extending at least partially between the first and second axial ends or at a plurality of contact sections spaced axially apart. The outer circumferential surface has a radius of curvature about equal to a radius of curvature of an outer surface of each one of the balls. Further, the annular body preferably also includes a plurality of annular grooves spaced axially apart, each annular groove extending radially inwardly from the concave outer circumferential surface and circumferentially about the centerline.

Low wear toroid separator for ball bearings

A separator for rolling elements of a bearing includes a body formed of a composite material and having a central pocket sized to receive one of a plurality of rolling elements, a first contact end to contact one adjacent rolling element and an opposing, second contact end to contact another adjacent rolling element. The composite material includes a mixture of a polymer base, reinforcing fibers and a lubricant, preferably, polyetherimide, short strand carbon fibers and molybdenum disulfide. The separator body is sized such that a first distance between a pocket centerline and the first contact end establishes a desired spacing distance between the rolling element within the pocket and the one adjacent one rolling element and a second distance between the centerline and the second contact end establishes a desired spacing distance between the rolling element within the pocket and the other adjacent rolling element.

Separator for rolling element bearings

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.

Vibration dampening for scanner bearing

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.

Rolling bearing

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.
