The Optibelt B 133 is a classical V-belt in the VB / Red Power series, built to a B profile with a 3454 mm length. Before you fit it, give the drive a quick inspection so the new belt starts on a clean, true-running basis.
Check the sheaves first. Look for worn grooves, a polished or bottomed-out groove face, and any burrs or nicks that will cut into a belt. A groove that has worn wide lets the belt sit too deep and slip; a groove that is choked with debris or old belt dust keeps the belt from seating at all. Wipe the grooves out and confirm the sheaves run true with no wobble or end play.
Then check alignment and tensioning. Misaligned sheaves, a bent shaft or a worn bearing will shorten belt life no matter what you install. Set the drive so the sheaves line up, and adjust the tensioner or motor slide through its full range before the belt goes on. If the old belt failed early, the cause is usually in the drive rather than the belt.
This belt measures 3454 mm in length, with a 17 mm top width, 11 mm height and a 40 degree angle. The same size is also listed under Stark B 133 and Mitsuboshi B 133. Send the part number by WhatsApp or email and we will confirm it or suggest an equivalent.
