FAQ

What is the purpose of the ‘2517’ designation?
The ‘2517’ specifies the size of the Taper Lock bush required to mount this pulley onto a shaft. This standardized system allows for a secure, keyed fit on various shaft diameters by simply changing the bush, not the pulley.

How do I determine the correct shaft size for this pulley?
The shaft size is determined by the bore of the 2517 Taper Lock bush you select. 2517 bushes are available with a wide range of metric and imperial bore sizes. You must choose a bush that matches your specific shaft diameter.

Can I use a different belt profile, like SPA or SPC, with this SPB pulley?
No, it is critical to match the belt profile to the pulley groove profile. This pulley is designed exclusively for SPB profile V-belts. Using an incorrect belt profile will lead to inefficient power transmission, excessive wear, and premature failure of both the belt and the pulley.
