		SHOULDER DESIGN Shoulder diameter When a bearing is located against a shoulder in the mating part, care must be taken that the rim of the shoulder clears the opposing ring. This is achieved when the diameter of the shoulder has clearance over the opposing race land diameter. Clearance should be > .010 inch (.25 mm) to allow for normal tolerances. Maximum shaft shoulder diameter = Outer ring land diameter* - clearance Minimum housing shoulder diameter = Inner ring land diameter* + clearance (Land diameters are given in the individual bearing.) Shoulder corner radius* The corner radius of the shoulder (ra) should be less than the fillet radius (r) of the mating bearing to allow the bearing to fully seat against the shoulder. The maximum shoulder corner fillet radii for bearings are given in the individual bearing tables.
