V-Belt Pulleys — Pilot Bore & Taper Lock
AIMS Industrial stocks V-belt pulleys from Finer Power Transmissions in a range of sections, materials and bore configurations. From light-duty aluminium pilot bore pulleys to heavy-duty multi-groove cast iron taper lock pulleys, we cover the breadth of industrial V-belt drive requirements across workshop, manufacturing, mining and OEM applications. Manufactured to ISO 4183 dimensional standards for SPZ, SPA, SPB and SPC narrow sections, and ISO 4184 for classical A, B, C and D sections.
For background on pulley types, drive selection, alignment and speed-ratio calculation, see our pulley types guide and pulley speed ratio reference.
Aluminium pilot bore pulleys
Aluminium pilot bore pulleys in A section (1 to 2 grooves) and B section (1 to 2 grooves) provide a cost-effective solution for lighter V-belt drives. The pilot bore is machined to your required shaft size in the workshop — typically with a keyway broached to match the shaft key. Aluminium pulleys offer a good balance of weight and performance for single-groove and light-duty multi-groove applications, and are particularly suited to vertical-shaft mountings where rotational mass matters.
Cast iron pilot bore pulleys
Cast iron pilot bore pulleys in SPA/A and SPB/B sections (1 to 2 grooves) are available where the durability of cast iron is required but the flexibility of a machined pilot bore is preferred. Heavier and more robust than aluminium equivalents, these suit moderate-duty industrial applications and motor drives where pulley life is paramount.
Taper lock V-pulleys
Cast iron taper lock pulleys are stocked in SPZ/Z/O/M (1-4 grooves), SPA/A (1-6 grooves), SPB/B (1-10 grooves) and SPC/C (1-12 grooves) sections. Taper lock hubs allow quick installation and removal without pulling tools or damage to the bore — a single taper lock pulley accepts multiple bush sizes, reducing the spares inventory required for a workshop or maintenance store. For complete background on taper lock specification, installation and removal, see our taper lock bush guide.
Pulley selection & alignment
V-belt pulley selection follows three core inputs: belt section (Z/A/B/C/D for classical, SPZ/SPA/SPB/SPC for narrow), number of grooves required for the drive power and groove pitch diameter. Pulley alignment between driver and driven is critical — even small angular or parallel misalignment significantly shortens belt life. Use a laser or straightedge alignment tool to confirm sheave alignment before final tensioning. For background on belt drive engineering and when V-belts are the right choice vs alternatives, see our belt vs chain drives guide.
