This page covers the Mitsuboshi SPZ 1437, a narrow wedge V-belt in the SPZ profile. If you are replacing a belt on an existing drive, the marking on the old belt is the fastest way to confirm you are ordering the same item.
Read the back of the belt you are removing. You are looking for the profile and the length together, so SPZ and 1437, not one without the other. The SPZ profile on this belt has a 9.7 mm top width, an 8 mm height and a 40 degree angle. Those three dimensions define how the belt sits in the pulley groove, so a belt with a different profile will not seat correctly even if it looks close.
Once you have the marking, send it to us by WhatsApp or email along with the quantity you need. We carry Mitsuboshi and can confirm the SPZ 1437 against your application. The same size is also listed under Stark SPZ 1437 and Optibelt SPZ 1437, so if your records show one of those numbers, it points to the same profile and length.
For drives running more than one belt, order the full set at the same time. Belts that have run together wear together, and mixing a new belt with used ones on a multi-belt drive changes how the load is shared across the grooves.
