2.5 with 5/8 bore @amazon.comThanks for the info. I was looking for a link belt at a good price and HF's price is perfect. I haven't been able to find a 2.5" diameter pulley at Grizzly but i found some good cast iron ones at Grainger.
For cost purposes I think I'm gonna pass on the double groove pulleys for now.
UPDATE: found a double groove 2" OD pulley but my craftsman TS specs list a 2.5" pulley. If i change both pulleys to 2" will my table saw explode?
