FAQ
The table lists 202 standard SPA pulleys: datum diameter 80–1000 mm, 1–6 grooves, all for Taper-Lock bush mounting (bush sizes 1210 / 1215 / 1610 / 1615 / 2012 / 2517 / 3020 / 3525 / 3535 / 4040 / 4545). Grooves are cut to DIN 2211 / ISO 4183; other diameters, groove counts and solid-hub versions are made to drawing.
SPA narrow V-belt pulley (Taper-Bush), reference diameter DP 80–1000 mm, 1–6 grooves; mounts with a Taper-Lock bushing for keyless quick fitting. Choose the section by power and pulley size: SPZ is the narrowest section for compact low- to medium-power drives, SPA and SPB cover mid-range fans, pumps and compressors, and SPC is for heavy, high-power drives with many grooves. All of these pulleys mount on a Taper-Lock bush, so one pulley fits many shaft sizes and comes off without a puller.
Yes. Everything on this page is made to drawing, and the table is only the standard-size subset of the catalogue. Minimum order quantity is one piece — we routinely make single replacement parts for OEMs whose original supplier has discontinued the item. Send a DWG, STEP or PDF drawing (or a sample part): you get a formal quotation within 24 hours after the information is complete, and the first article ships within 30 days of drawing approval, with inspection records.
Send the drawing or: belt section (SPZ/SPA/SPB/SPC or classical A/B/C), datum diameter, number of grooves, Taper-Lock bush size and bore (or solid hub with bore and keyway), material, balancing requirement and quantity. If you are matching an existing drive, the other pulley's size and the belt length help us check the ratio.
