We can produce the whole series of taper bore v-pulleys: SPA,SPB,SPC and SPZ. They are made of high grade GG25 cast iron, with a delicate finish and assembled precisely. They can also be matched with BTL Bushings with easy on and easy off capabilities and practical utility. They are suitable for all kinds of power transmission installation.
Mount these pulleys with a taper-lock bushing for a tight, wobble-free hold on your shaft. These pulleys transfer force from the shaft to a V-belt in a power transmission system, and also help with misalignment. Made of cast iron, these pulleys are durable and resist wear.
Depending on the taper-lock bushing you choose, the same pulley can be used with different shaft diameters.
