A loader slot bearing includes a housing and a truncated ball. The housing has an interior area that is defined by an inner bearing surface which has a concave contour defining a circumference. A single slot extends axially partway into the inner bearing surface and has a slot arc section area extending axially inward. The slot arc section area has a first circumferential slot-end, a second circumferential slot-end, and a slot arc length measured between the first circumferential slot-end and the second circumferential slot-end. A ratio of the slot arc length to the circumference of the interior area is about 0.20 to 0.35. The truncated ball has a convex exterior surface. The truncated ball is positioned in the slot and rotated so that the truncated ball is rotatably retained by the inner bearing surface. The truncated ball is angularly misalignable relative to the annular housing.

Single slot loader slot bearing

A loader slot bearing includes an annular housing having first and second axial surfaces and an interior area extending therebetween. The interior area has a first inner surface that extends between the first and second axial surfaces. A portion of the inner surface is a first bearing surface that has a spherical contour. A slot extends partially into the first inner surface from the first axial surface. The slot has a first width. The annular housing is manufactured from a precipitation hardened corrosion resistant stainless steel. The loader slot bearing includes a truncated ball that is positioned in the slot and rotated so that the truncated ball is rotatably retained by the first bearing surface. The truncated ball is angularly misalignable relative to the housing and is manufactured from a 440C stainless steel. A dry lubricant is applied to the spherical exterior surface of the truncated ball.
