Note: J is the bolt hole's center line dimension, and P,C,D. A2 is distance between the center line of spherical bore diameter of the housing and mounting surfaces, and H3 is
outside diameter of the spigot joint. Radial runout of spigot joint is applied for flange units with spigot joints. This table can be applied for bearing units with dust covers.
