The Optibelt SPB 1850 is a narrow wedge V-belt in the SK metric profile line. It measures 1850 mm in length with a 16.3 mm top width, 13 mm height and a 40 degree angle. Narrow wedge belts like this one are common on industrial drives where a compact profile carries the load across a smaller pulley set.
Confirming fit starts with the belt you are replacing. Read the marking on the back of the old belt: the profile and length should match SPB and 1850 mm. Check the top width and height against the 16.3 mm and 13 mm figures above, and confirm the pulley grooves are cut for a 40 degree wedge belt rather than a classic V profile. If the drive uses several belts, order the full set so the load stays even across the grooves.
Inspect the drive before ordering. Look for worn or misaligned pulleys, oil or heat exposure, and any debris in the grooves, since these shorten belt life. A belt that has run hot or slipped will show glazing or cracking on the sides. If the old belt number is unreadable, note the pulley diameters and center distance and send those along with your request.
The same size is also listed under Stark as SPB 1850. Send the part number, quantity and any marking details by WhatsApp or email and the team will confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Match the SPB profile and 1850 mm length to the marking on your old belt, and check the 16.3 mm top width and 13 mm height. If the number is worn off, send the pulley diameters and center distance instead.
- Should I replace all belts on the drive at once?
- On a multi-belt drive, replacing the full set keeps tension and load sharing even. Mixing a new belt with worn ones can overload the new belt and shorten its life.
