FAQ
Common questions about this series
SPZ narrow V-belt pulleys: what size range does the table cover?
The table lists 181 standard SPZ pulleys: datum diameter 63–630 mm, 1–6 grooves, all for Taper-Lock bush mounting (bush sizes 1108 / 1210 / 1610 / 2012 / 2517 / 3020 / 3030). Grooves are cut to DIN 2211 / ISO 4183; other diameters, groove counts and solid-hub versions are made to drawing.
SPZ narrow V-belt pulleys: what is it and when should I use it?
SPZ narrow V-belt pulley (Taper-Bush), reference diameter DP 63–630 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.
SPZ narrow V-belt pulleys: can I order a size that is not in the table, or just one piece?
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.
SPZ narrow V-belt pulleys: what do I need to send to get a quote?
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.
