Description
MITSUBOSHI SPA 3550 belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SPA 3550 and any equivalents.
The Mitsuboshi SPA 3550 is a narrow wedge V-belt in the SPA profile. Its 12.7 mm top width, 10 mm height, 40° angle, and 3550 mm length identify the belt for buyers matching an existing drive.
The SPA profile is the controlling dimension when you select a replacement. A 12.7 mm top width, 10 mm height, and 40° angle mean the belt fits a sheave groove cut for SPA. The 3550 mm length sets the center distance the drive was built around. If either the profile or the length is wrong, the belt will not seat or tension correctly.
The same size is also listed under Optibelt SPA 3550, so that is another brand to compare when you are sourcing. For a quote, send the part number SPA 3550 and the quantity. If you are replacing a belt on an existing drive, check the marking on the back of the old belt and share that with us so we can confirm the profile and length.
We carry the Mitsuboshi SPA 3550 and serve maintenance, engineering, and purchasing teams across the United States, Canada, Mexico, and South America. Quotes are handled by WhatsApp or email, and we reply promptly to confirm the right belt or suggest an equivalent.
