The Optibelt C 173 KB is a banded V-belt built for drives that run several V-grooves side by side. The band ties the individual belts together so they stay aligned and share the load across the sheave. This page covers where this type of belt is used and how to confirm it fits your drive.

Banded V-belts are common on industrial drives where a single belt would slip or where matched sets are difficult to keep in step. Typical equipment includes fans, blowers, compressors, mixers, crushers and process machinery driven by multiple-groove pulleys. The band keeps the belt set from turning over or jumping out of a groove when the drive sees pulsating or shock loads.

To confirm fit, start with the marking on the back of the old belt. Read the profile and the length exactly as stamped, then compare them with the drive sheave grooves and the center distance. Check the sheave grooves for wear, and inspect the belt for cracks, missing ribs or a loose band. If the marking is worn away, measure the outside length and the top width, and count the grooves on the sheave.

Replace banded belts as a complete set, never one strand at a time. Mixed wear or mismatched lengths will cause the new belt to carry more than its share and fail early. After installation, check tension and re-check it after the first hours of running. Send the belt marking or your measurements by WhatsApp or email and we will help confirm the right banded belt or suggest an equivalent.
