The Optibelt B 50 KB is a banded V-belt with a 1346 mm length. Banded construction ties multiple V-belts together so they run as a set on drives with several grooves. This belt is suited to industrial drives where matched sets are needed to keep pulleys aligned and reduce vibration.
Banded V-belts are used on drives that carry more than one belt per pulley, such as large fans, pumps, and compressors. The band holds the individual belts at a fixed spacing, which helps prevent flipping and uneven wear. To confirm fit, check the old belt's marking for the profile and length, and measure the outside length if the marking is worn. The B 50 KB has a 1346 mm length and a B profile.
When replacing a banded belt, inspect all pulley grooves for wear, rust, or debris. Replace the full set at once; mixing new and used belts on the same drive can cause the band to fail. Confirm the number of ribs or grooves on the drive matches the belt's construction. If you are unsure of the correct part, send the belt marking, pulley dimensions, and drive details for a quote.

Frequently asked questions
- How do I confirm the B 50 KB fits my drive?
- Check the marking on the old belt for the profile and length. The B 50 KB is a B-profile banded belt with a 1346 mm length. Also confirm the number of grooves on the pulleys matches the belt.
- Can I replace only one belt in a banded set?
- No. Banded V-belts are designed to be replaced as a complete set. Replacing only one belt can cause uneven tension and premature failure of the band.
- What information should I send for a quote?
- Send the part number B 50 KB, the belt marking, the number of grooves, and the pulley diameters. Photos of the drive and old belt also help confirm the correct replacement.
