This standard for spherical bearings, joint type (without rolling elements) has been established for the purpose of defining the characteristics of these bearings such as boundary dimensions, tolerances and terminology. This style of bearing consists of an outer ring having an inner concave sphered sliding contact surface and an inner ring having a matched outer convex sphered sliding contact surface. Two general styles, related to manufacturing method are included, swaged (1.2) and fractured (1.3).
This style of bearing is manufactured utilizing a“swaging” or forming of the outer ring over the inner ring (ball).These bearings are Series 1 and 2 in this Standard.
This style of bearing has the outer ring split or fractured in one position to facilitate manufacturing assembly of the rings.These bearings are Series 3 in this Standard.
That part of a spherical plain bearing, joint type, having a convex sphered outer surface and a cylindrical inside surface.
That part of a spherical plain bearing, joint type, having a concave sphered inner surface and a cylindrical outside surface.
An outer ring manufactured and assembled in one piece., i.e., not divided or split in anyway.
A one piece outer ring manufactured by deformation of the outer ring material around the inner ring to obtain the sphered inner surface.
An outer ring manufactured in one piece and subsequently split or fractured in one position in an axial plane, to facilitate manufacturing assembly.
That surface of an inner ring intended to make sliding contact with an outer ring and having the form of part of the outside surface of a sphere whose center lies on the bearing axis.
That surface of an outer ring intended to make sliding contact with an inner ring and having the form of part of the inside surface of a hollow sphere whose center lies on the bearing axis.ABMA 22.2 pdf free download.
