A sheave refers to a grooved wheel that is used together with a belt or chain to control the pulling force in pulleys. Poly V sheaves use Poly V belts, and they have V-shaped grooves that provide higher traction than other types of sheaves
. The angle of the groove affects the belt traction and performance such that traction is higher when the groove angle decreases. They are the compact alternative to standard V sheaves, and they can use only one belt to transmit up to 600KW. Poly V sheaves run quietly and are ideal for application areas such as in agricultural machinery, exercise equipment, dryers, fans, medical equipment high-speed machine tools, centrifuges and polishers. Poly V sheaves can be designed to feature any number of grooves, split taper or standard bushings
, and standard or custom keyseats. They can also be made from various materials such as steel, aluminium, cast iron, and stainless steel. They require little maintenance and their belts are highly resistant to wear and tear.Get the best selection of Poly V Sheave from MRO Supply. We stock a wide range of sheaves to suit any application.
