The Optibelt 5-B 3700 is a banded V-belt in the KB VB series, built for drives that use multiple V-belts side by side. Its 3700 mm length and banded construction keep the belts aligned as one unit. Before fitting a replacement, inspect the drive and sheaves so the new belt runs true from the start.
Check sheave grooves for wear, rust, or embedded debris. Worn grooves let the belt sit too deep, which shortens belt life and can slip under load. Confirm that all sheaves are aligned and that the driven equipment turns freely by hand. If any sheave is damaged, correct it before installing the Optibelt 5-B 3700.
On a banded V-belt, the tie band holds the individual belts together, so the set must be matched to the sheave grooves across the full width. Measure the existing belt's length and compare it to the 3700 mm figure. Clean the grooves, then fit the belt without prying it over the sheave edges, and tension it according to your drive manufacturer's procedure.
After running the drive briefly, recheck tension and look for uneven seating or unusual noise. Banded belts are commonly used where pulsating or shock loads would cause single belts to whip or turn over. If you need to confirm the right belt for your drive, send the part number and the details from the old belt's back.
