r : Chamfer Dimension of Inner/Outer Ring
r 1 : Chamfer Dimension of Inner/Outer Ring (Front Side) or of Central Washer of Thrust Ball Bearings
Remarks : The precise shape of chamfer surfaces has not been specified but its profile in the axial plane shall not intersect an arc of radius r (min) or r 1 (min) touching the side face of an inner ring or central washer and bore surface, or the side face of an outer ring and outside surface. |
