Description
MITSUBOSHI SPA 1900 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 1900 and any equivalents.
This Mitsuboshi SPA 1900 is a narrow wedge V-belt with an SPA profile and a length of 1900 mm. The 12.7 mm top width, 10 mm height, and 40-degree angle define a belt that fits drives designed for the SPA cross-section. Use the profile and length to confirm it matches the belt you are replacing.
The SPA profile is a narrow wedge cross-section, so the belt runs in SPA pulleys and transmits load through the wedge shape rather than a classic V profile. The 1900 mm length is the datum you need when checking the drive layout or reading the marking on the old belt. If the existing belt shows SPA 1900, this is the same size.
The same size is also listed under Stark SPA 1900 and Optibelt SPA 1900, so you can compare those part numbers if your maintenance records use a different brand. For a quote, send the part number SPA 1900 along with the quantity and any details from the drive nameplate. If you are unsure of the cross-section, a photo of the old belt and the pulley groove helps confirm the SPA profile.

Frequently asked questions
- What do the SPA profile and 1900 mm length mean for my drive?
- SPA is the narrow wedge cross-section, and 1900 mm is the belt length. Both must match the pulley groove and the drive layout for the belt to fit and run correctly.
- How do I confirm this is the right belt before ordering?
- Check the marking on the back of the old belt for SPA 1900. You can also measure the top width and height, but the SPA 1900 marking is the simplest reference.
- What should I send to request a quote?
- Send the part number SPA 1900, the quantity you need, and any drive details you have. If you want us to confirm the profile, include a photo of the old belt and the pulley.
