The Optibelt BX 77 KB is a banded V-belt from the KBX series, built with a 2032 mm length. Banded construction ties multiple V-belts into one unit, which keeps them running as a set on drives that use several belts side by side. This belt is suited to industrial drives where matched belt sets are required.
Banded V-belts are common on drives with multiple grooves, such as fans, pumps, compressors and process machinery. Because the belts are joined across the top, the assembly resists flipping and keeps the individual belts from jumping out of their grooves. The BX profile is a narrow V-belt cross-section, and the 2032 mm length is the datum length for this part.
To confirm fit, read the marking on the back of the old belt and compare it with BX 77 KB. Check the belt profile against the pulley groove and measure the length as marked. If the old belt is worn or stretched, use the part number rather than a measurement from the used belt. Send the part number and any photos of the marking to our team for a quote.
