PJ Poly-V-Belt Pulleys

PJ Poly-V-belt pulleys are the basic type of poly-V-belt pulleys. They are produced in standard series and dimensions of gray cast iron or they are custom made according to drawings or customer requirements.

Their design is based on ISO 9982 and DIN 7867 standards.

The pulleys are usually mounted on shafts using the Taper bush. Only smaller sizes are supplied as a semi-finished product and the bore must be modified before mounting the pulleys on the shafts.
