Description
Single or multi V-belt pulleys they are used to transmit power or change the rotational speed in a given application. The working material is cast iron, which is characterized by durability and corrosion resistance. This version is available from stock. The combination of the pulley with steel TaperLock bushings allows for quick assembly without additional processing.
The TaperLock sleeve is a small element that has been equipped with a cylindrical hole and a spline groove. Its use facilitates and accelerates the assembly and disassembly of wheels on the axes of engines and allows their precise centering on the shaft. Thanks to the high clamping force, it tightens in the hub and allows to transfer high torques.
