The Mitsuboshi SPZ 3550 is a narrow wedge V-belt for industrial drives that need a compact, high-capacity profile. It is built to the SPZ profile with a 9.7 mm top width, 8 mm height and 40-degree angle. Use it where original equipment or a replacement callout specifies an SPZ section belt.
Narrow wedge belts like this SPZ section are common on pumps, fans, compressors and other packaged equipment where space is tight and speeds are higher than a classic V-belt drive. The 3550 mm length is the datum to match against the old belt or the drive documentation. Confirm the sheave groove is cut for an SPZ profile and that the belt sits correctly in the groove before ordering.
The same size is also listed under Optibelt SPZ 3550 and Gates SPZ 3550, which can help when comparing a marking on a removed belt. Check the back of the old belt for the profile and length marking, then send that part number to our team. We can confirm the SPZ 3550 or suggest an equivalent based on the data you provide.

- Can I replace a belt marked with another brand?
- If the old belt is marked SPZ 3550, the same size is also listed under Optibelt and Gates. Send us the marking and we can help confirm the Mitsuboshi SPZ 3550 or suggest an equivalent.
