D suffi x has a groove with oil holes for lubrication through the outer ring
CD suffi x now replaces the DC suffi x listed for part numbers in previous publications. Same features as D suffi x, but CD also has groove with oil holes. One lubrication hole is counterbored to accept an anti-rotational pin.
