This Optibelt SPZ 1437 is a narrow wedge V-belt in the SK metric profile series. It is used on compact, high-speed industrial drives where a standard-profile belt would be too wide or heavy. If you are replacing a worn SPZ belt, confirm the profile and length before you order.
The SPZ profile measures 9.7 mm across the top and 8 mm high, with a 40-degree angle. The datum length is 1437 mm. These dimensions suit drives with small pulleys and short center distances, such as machine tools, pumps, fans and light industrial equipment. Because narrow wedge belts run in the same groove family as other SPZ belts, the profile is the first thing to check on the old belt or in the drive documentation.
To confirm fit, read the marking on the back of the belt. It should show SPZ and 1437. If the old belt is unmarked, measure the top width and the outside length, or check the pulley groove and the drive specification. The same size is also listed under Stark SPZ 1437 and Mitsuboshi SPZ 1437, so those brands can be used as a reference when you match the size.
When you request a quote, send the part number Optibelt SPZ 1437, the quantity, and any drive details you have. If you are unsure whether this is the correct belt, send a photo of the old belt marking and the pulley grooves, and we will help confirm the profile and length or suggest an equivalent.
