V-belt pulleys or grooved pulleys represent a key component of V-belt drives. Made of cast iron, they are available undrilled, pre-drilled or with a clamping bushing.
Grooved pulleys for narrow V-belts, classified according to DIN 7753, can also be used with classic V-belts according to DIN 2215 with the same reference width. These V-belt pulleys are therefore also referred to as unit pulleys.
Please refer to the respective data sheet for more detailed properties of the individual components.
