SPA section 1 groove taperlock V & wedge pulley suitable for A section, AX section, SPA section, XPA section and A section Nutlink V belts and wedge belts
They are manufactured from grade GG25 cast iron with a black phosphated finish for corrosion resistance. A pulley drive allows mechanical power, torque, and speed to be transmitted across mating shafts. If the pulleys are of differing diameters, a mechanical speed increase or decrease is achieved. The pulley is pre-machined to suit a size 1008 taper lock bush centre for easy mounting.
Pulley groove specification conforms to ISO4183.
Suitable for both classical and wedge belts.
Larger pulleys, weighing in excess of 100kg are dynamically balanced.
