Description
MITSUBOSHI SPA 1250 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 1250 and any equivalents.
This Mitsuboshi belt is an SPA profile narrow wedge V-belt with a 1250 mm length. The SPA profile is defined by a 12.7 mm top width, 10 mm height and 40 degree angle. The same size is also listed under Optibelt SPA 1250.
For a maintenance or purchasing professional, the profile and length are the two values that decide whether this belt fits the drive. SPA sets the cross-section and the groove it seats in; 1250 mm sets the outside length around the pulleys. Both are stated on the belt and in the drive documentation, so they are the fastest way to confirm a match before ordering.
When you request a quote, send the part number SPA 1250 and the Mitsuboshi brand. If you are replacing a belt on an existing drive, the marking on the back of the old belt gives you the same profile and length to compare. The same size is also listed under Optibelt SPA 1250 if you are cross-checking a drive that uses that brand.
Narrow wedge V-belts like this SPA profile are used where a standard V-belt section would be too wide for the pulley groove. Inspect the pulleys for wear and alignment, and replace belts in sets when the drive uses more than one belt so the load stays even across the grooves.

Frequently asked questions
- What do the profile and length mean on this belt?
- SPA is the profile: a narrow wedge cross-section with a 12.7 mm top width, 10 mm height and 40 degree angle. The 1250 mm is the belt length. Match both to the drive.
- How do I confirm this is the right belt for my drive?
- Read the marking on the back of the old belt. If it shows SPA and 1250 mm, this belt matches that profile and length. You can also measure the pulley groove and the drive center distance, but the marking is the direct check.
- What should I send to request a quote?
- Send the part number SPA 1250 and the brand Mitsuboshi. If you have the old belt, include a photo of the back marking so the profile and length can be confirmed.
