Abstract
A rod end includes a shaft and a head extending from the shaft. The head has an opening extending therethrough. The rod end includes a spherical bearing rotatably disposed in the opening. The spherical bearing is manufactured from an austenitic stainless steel alloy that includes 16 to 17 weight percent chromium and 0.1 to 0.18 weight percent nitrogen.
Claims28
A rod end comprising:
- a shaft having a first end and a second end;
- a head extending from the shaft at the first end, the head having an opening extending between a first axial face and a second axial face thereof;
- a spherical bearing rotatably disposed in the opening, the spherical bearing being manufactured from an austenitic stainless steel alloy comprising 16 to 17 weight percent chromium and 0.1 to 0.18 weight percent nitrogen;
- and
- wherein the shaft and head comprise an austenitic nickel-chromium-based stainless steel alloy comprising 50-55 wt % nickel and 17-21 wt % chromium;
- a wear mitigation feature bonded to at least one of the first axial face and the second axial face, the wear mitigation feature comprising a self-lubricating liner;
- the wear mitigation feature having an area of a magnitude configured to cover at least a portion of at least one of the first axial face and the second axial face;
- and
- wherein the wear mitigation feature extends from the opening to a distal edge of the head.
