Abstract: A rolling element bearing includes a plurality of rolling elements, a bearing inner ring and a bearing outer ring. The rolling elements are arranged circumferentially around an axis, and radially between the inner ring and the outer ring. The inner ring includes a plurality of first passages, a second passage and a channel that extends axially into the inner ring. The first passages are arranged circumferentially around the axis. The first passages respectively extend axially through the inner ring from a plurality of first passage inlets to the channel. The second passage includes a second passage inlet that is substantially axially aligned with one of the first passage inlets. The second passage extends radially through the inner ring to a second passage outlet.

Abstract: An apparatus is disclosed for applying heat and pressure to a contusion. The disclosed apparatus comprises a housing, at least one roller, and a heating element. The heating element is configured to heat the roller, and the roller is configured to be applied to a contusion.

Abstract: A rolling element bearing includes a plurality of rolling elements that are arranged circumferentially around an axis, and radially between a bearing inner ring and a bearing outer ring. The inner ring extends axially between a first end and a second end, and includes a plurality of passages that are fluidly coupled with a channel. The passages are arranged circumferentially around the axis. The channel extends axially into the inner ring from the second end, and includes a gutter that extends radially into and axially within the inner ring.

Abstract: A lubrication system for a bearing assembly includes a fan shaft with a plurality of conduits, a first bearing rotatably supporting the fan shaft, and a second bearing rotatably supporting the fan shaft where the second bearing is axially spaced from the first bearing. The plurality of conduits includes at least a first conduit aligned with the first bearing and a second conduit aligned with the second bearing. A spray bar includes a plurality of supply orifices that direct lubricating fluid to the first and second bearings via at least the first and second conduits.

Abstract: A bearing assembly includes an inner ring, an outer ring, a plurality of roller elements disposed between the inner ring and outer ring and spaced tangentially apart from each other by a cage. The inner ring includes a rib annulus. The rib annulus provides a flow of lubricating fluid around the rib face.
