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.

12/SPZ1800 Optibelt Kraftband V-Belt
The Optibelt Kraftband 12/SPZ1800 is a 12-band SPZ section banded V-belt with a 1800mm pitch length. It runs in 12 adjacent SPZ pulley grooves and is made by Optibelt in Germany, our premier brand.
Kraftbands are made from high-quality wrapped V-belts joined by a tough tie band across the top. That stops individual belts turning over or jumping off the pulleys, so they’re the answer for drives with heavy shock loads, long centre distances, vertical shafts or vibration.

Check it’s the right belt
- The old belt should be marked 12/SPZ 1800 or 12-SPZ1800. The first number is how many bands. The letters are the section and the number is the pitch length in mm.
- Count the grooves on the pulley and check the pulley groove spacing suits a Kraftband. Kraftbands need pulleys with standard groove spacing.
- Each band is 9.7mm across the top. Measure one band, not the whole belt.
Need a different size? The nearest lengths are 12/SPZ1700 and 12/SPZ1900, or see all 12-band belts. The same length is also available as 10-band (10/SPZ1800). Not sure? Call 020 8138 2848 and we’ll help you find the right belt.
