V-Pulleys

V-pulleys are grooved wheels whose angled rim channels guide matching V-belts and transfer torque to or from a shaft. Single or multiple grooves support one belt or matched sets, while solid, webbed and spoked bodies suit different diameters and drive arrangements.

Questions about v-pulleys

What should I send to identify v-pulleys?

Send belt groove profile, pitch or outside diameter, groove count, bore and keyway, shaft speed. Measure groove geometry as well as outside diameter because classical and wedge profiles can look similar after wear. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select v-pulleys?

Match groove standard, diameter, count, material, bore and balance needs to the selected belts and drive speed. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
