The Stark B 77 is a classical V-belt with a B profile, a 17 mm top width, an 11 mm height and a 40 degree angle. It is one of the belts we carry for industrial drives, and this page covers what to check on the drive before you fit it.

Before fitting a new belt, inspect the sheaves. Look for worn groove flanks, a polished or bottomed-out groove, cracks, and any build-up of debris or oil. A worn sheave lets the belt sit too deep, so it slips and wears out early even when the belt itself is correct. Check that the sheaves are aligned and that the belt runs straight in the grooves.

Check the rest of the drive at the same time: keys, bushes, bearings, and the tensioning arrangement. Confirm the replacement matches the belt you are removing by reading the marking on the back of the old belt, including the profile and the length. The Stark B 77 is a B profile belt, 17 mm across the top, 11 mm high, with a 40 degree angle. The same size is also listed under Optibelt B 77.

When you request a quote, send the part number B 77 and the quantity you need. If you are unsure whether this is the right belt for the drive, send the marking on the old belt and a photo of the sheave, and the team can confirm the profile and length or suggest an equivalent.
