I have a 5/8" shaft on a table saw arbor with 1-1/4" of available seating length for the pulley. From your product literature, dimension "L" is 1-31/32 inches on your Type 1 2BK pulleys that I am considering for my saw. What is the minimum recommended shaft length for these pulleys? That is, would a shaft that penetrates just 1-1/4" be sufficient? Thanks!
A: It would not be recommended to use this pulley on that short of a shaft. Only one groove would be supported by the shaft, with the other groove lying completely off of the shaft.

I would like to make sure before I order that this is an A groove double belt pulley.
A: These pulleys are cut for both A and B belts. A belts sink in the groove deeper, but do not bottom out.
