This Optibelt SPA 1257 is a narrow wedge V-belt in the SK metric profile series. The SPA profile and 1257 mm length identify the belt for your drive. Use the marking on the old belt to confirm the part number before you request a quote.
The SPA profile is a metric narrow wedge section. This belt has a 12.7 mm top width, a 10 mm height and a 40° angle. The length is 1257 mm. These values are the ones to match when you compare the belt on the drive.
For a correct quote, send the part number SPA 1257 and the quantity you need. If the old belt is worn or the marking is hard to read, measure the top width, height and length and include those figures. We carry Optibelt belts and can help confirm the right belt or suggest an equivalent.
Inspect the drive before ordering. Check the sheave grooves for wear and the other belts in the set for matching profile and length. Replace belts in sets where the drive uses multiple belts.
