The Optibelt SPA 1907 is a narrow wedge V-belt in the SK metric profile series. Its SPA profile and 1907 mm length identify it for drives built to metric dimensions. The 12.7 mm top width, 10 mm height and 40° angle define the groove it fits.

Profile and length are the two dimensions that decide fit. SPA is the metric narrow wedge profile; the 1907 mm length is the datum length for this belt. The 12.7 mm top width and 10 mm height show how it seats in a matching SPA pulley groove, and the 40° angle is the included angle of the belt cross-section. If the drive was designed around an SPA section, these numbers are what you check before ordering.

The cleanest way to confirm a replacement is to read the marking on the back of the old belt. Look for the profile and the length together, such as SPA and 1907, and compare them with the top width and height above. A belt that has stretched or worn can measure differently from its original marking, so use the printed code as the primary reference and the physical dimensions as a cross-check.

For a quote, send the part number Optibelt SPA 1907, the quantity, and the drive or equipment it serves. If the old belt is unmarked or the profile is unclear, a photo of the belt and pulley grooves helps us confirm the section. We carry Optibelt belts and can help match the correct narrow wedge V-belt to your drive.
