Stepped Aluminium V Pulleys - Pilot Bore
Transmissions V & Wedge Pulleys Aluminium Pulleys
Our range of stepped aluminium V pulleys with pilot bore offers versatile power transmission solutions for variable speed applications. Available in SPZ, SPA and SPB belt sections, these precision-engineered pulleys feature multiple diameter steps (3 or 4) ranging from 40mm to 200mm PCD, allowing for quick speed changes on the same drive system. Each pulley is manufactured from high-quality aluminium and comes with a blank pilot bore that can be machined to your required shaft size, with maximum bore capacities from 23mm to 40mm depending on the model. Perfect for industrial machinery, workshop equipment, and power transmission applications where multiple operating speeds are needed, these pulleys are supplied with boss lengths between 44mm and 68mm to ensure secure mounting and reliable performance.
