    Abstract: A bearing assembly includes an inner member having an outer engagement surface and an outer race. The outer race has an inner surface defining a first end and a second end and an inner engagement surface therebetween, the inner engagement surface is positioned on the outer engagement surface of the inner member. A first annular groove is formed in the inner surface, proximate one of the first end and the second end. A second annular groove is formed in the inner surface and is positioned axially inward from the first annular groove. An external seal is positioned in first annular groove and slidably engages the inner member. An internal seal is positioned in the second annular groove and slidingly engages the inner member.

    Abstract: A spherical plain bearing includes an outer ring having a concave interior spherical surface, and an inner member having a convex exterior spherical surface. The inner member is pivotally disposed in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another. The spherical plain bearing includes an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member. The first and second portions are spaced apart when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ, and come into abutment when the inner member and the outer ring are angularly misaligned relative to one another by angle θ. The abutment prevents any further relative angular misalignment of the inner member and the outer ring.

    Abstract: A spherical plain bearing includes an outer ring and an inner ring that are each coaxial with a longitudinal axis of the bearing. The outer ring has a first axial outer ring end, a second axial outer ring end, and an interior spherical concave bearing surface extending therebetween. The inner ring has a first axial inner ring end, a second axial inner ring end, and an interior cylindrical bearing surface defining a bore and an exterior spherical convex bearing surface extending therebetween. The exterior spherical convex bearing surface is in interfacial sliding engagement with the interior spherical concave bearing surface. A plurality of circumferential lubrication grooves and one or more curved lubrication channels are in the exterior spherical convex bearing surface. The curved lubrication channels are positioned to intersect each of the circumferential lubrication grooves. A plurality of profiled annular lubrication grooves circumferentially extend into the interior cylindrical bearing surface.

    Abstract: A suspension system for a rail car has at least two undercarriage members and at least one equalizer bar removably and pivotally secured to and between the two undercarriage members. A spherical bearing has an outer member that surrounds an inner member. The outer member is removably secured to one of the undercarriage members. The inner member is removably secured to the equalizer bar. The outer member defines at least one outer member section having an arcuate interior surface and the inner member defines at least one inner member section having an arcuate exterior surface. A low friction liner is disposed on at least one of the arcuate interior surface or the arcuate exterior surface.

    Abstract: A spherical bearing includes a split outer ring having a spherical radially inner facing surface, an axially outward facing shoulder and a radially outward extending first groove formed therein. A first snap ring is snap fit in the first groove. The spherical bearing includes an inner race defining a spherical exterior surface and having a radially inward extending second groove. A second snap ring is snap fit into the second groove. A seal extends between the outer ring and the inner race and includes a retaining ring secured to a second end of the seal. A first end of the seal defines a lip extending radially inward. The lip is seated against the second snap ring. The retaining ring is positioned between the first snap ring and the axially outward facing shoulder. The seal is axially compressed between the axially outward facing shoulder and the second snap ring.
