Fixed-bore die-cast V-belt pulleys have a finished bore, or center hole, that is machined to a set diameter to insert a shaft of the same size. They are ready to install with machined keyways and/or set screws to secure the shaft and prevent slipping. These zinc die-cast pulleys are non-corrosive, lightweight, impact-resistant, and non-toxic. They are suitable for light duty applications such as fans and blowers in HVAC applications.

Fixed-bore composite V-belt pulleys have a finished bore, or center hole, that is machined to a set diameter to insert a shaft of the same size. They are ready to install with machined keyways and/or set screws to secure the shaft and prevent slipping. Composite pulleys are constructed of fiberglass-reinforced nylon that withstands high temperatures and abrasion. They are lightweight, corrosion resistant, and are often used in conveyor applications that require washdown.

Bushed-bore cast-iron V-belt pulleys need a bushing to mount to the drive shaft and adapt the bore, or center hole, to the shaft size. They are constructed of cast iron which has good wear resistance and absorbs heat.

Bushed-bore cast-iron wedge V-belt pulleys need a bushing to mount to the drive shaft and adapt the bore, or center hole, to the shaft size. They are constructed of cast iron which has good wear resistance and absorbs heat. These pulleys are designed for wedge V-belts which are designated with a "V" and have a deeper profile allowing it to transfer higher power than classical V-belts.
