Measuring Your Belt
Measuring Your Belt
Check the markings first. Most belts have their size printed on the back, for example A24, SPZ1000 or 8PK1200. Type that code into the search bar to find the exact match.
Markings worn off? Measure across the top of the belt for the width, and its depth. For the length, wrap a piece of string round the belt, mark where it meets, then lay the string flat and measure it.
Timing or ribbed belt? Count the teeth or ribs, and measure the gap between them.

SPB 250 x 8 Groove Taper Lock Pulley - 3535 Bush
SPB 250 x 8 Groove Taper Lock Pulley - 3535 Bush is backordered and will ship as soon as it is back in stock.
The SPB250/8 is a 8-groove SPB taper lock pulley with a 250mm pitch diameter. It runs SPB wedge belts and B (17mm) classical V-belts.
It takes a 3535 taper lock bush, which takes shafts from 35mm to 90mm in standard metric bores. The bush is sold separately: choose a 3535 bush in your shaft size and the pulley can be fitted and removed without machining.
It’s made from cast iron (EN-GJL-200) with grooves to ISO 4183 and DIN 2211, black phosphated against corrosion, and statically balanced for belt speeds up to 35m/s.

Check it’s the right pulley
- The old pulley should be marked SPB250/8 or SPB 250 x 8, and the bush 3535.
- Measure across the outside of the rim: about 257mm. The pitch diameter is smaller because it’s measured where the belt sits in the groove.
- Check your belts are SPB (or the matching classical section) and you need 8 grooves.
Not quite the right size? The nearest diameters with 8 grooves are SPB236/8 and SPB265/8. Not sure? Call 020 8138 2848 and we’ll help you find the right pulley.
