Cast-iron taper-bushed timing pulleys for quick mounting and reliable shaft grip. Fits standard taper bushes (1108 / 1210 / 1610 / 2012) so the same pulley can be mounted on different shaft diameters.
Taper-bushed timing pulleys cut inventory: a single pulley body fits any shaft diameter that has a matching taper bush — far simpler than stocking separate bore-and-keyway pulleys for every shaft size.
