Abstract
An exemplary method for limiting movement of an outer race of a bearing cartridge includes positioning the bearing cartridge in a substantially cylindrical bore having a longitudinal axis, an inner diameter exceeding an outer diameter of the outer race, a proximate end and a distal end; limiting axial movement of the outer race at the distal end of the cylindrical bore with a counterbore substantially coaxial to the cylindrical bore and having an inner diameter less than the outer diameter of the outer race; limiting axial movement of the outer race at the proximate end of the cylindrical bore with a plate positioned substantially orthogonal to the longitudinal axis; and limiting rotation of the outer race with a pin positioned in a pin opening accessible via a lubricant drain. Various exemplary bearing cartridges, housings, assemblies, etc., are also disclosed.
