Outside Diameter Diameter measured at the outside of the pulley.
Datum Diameter The datum diameters are an industry standard reference point used for calculations such as center distance and belt length. The datum system replaces the pitch system for classical belts and pulleys to compensate for differences in manufacturers construction of belts.
Does an A belt ride above or below the O.D. of the pulley?
A: This pulley is cut for a 5/8" belt and 1/2" belt. The 1/2" belt will ride dipper in the grove so it will ride below the O.D. of the pulley.

Do you carry a v belt to fit this pulley?
A: The pulley will accept both A and B belts to ride in the groove. If you mean a belt that would roll on to be used in a bandwheel type application, the circumference is approximately 43.175". A belt that is 43" on the back side would be too small and would not roll on. A belt that is 44" on the back side would be too loose and would spin in the groove. It is unknown if either would fit or work in that application.
