The Optibelt B 120 KB is a banded V-belt with a 3124 mm length. This page covers what the profile and length tell you when specifying or replacing a belt.
The B profile indicates a classic V-belt cross-section, and the banded construction ties multiple belts together to run as a single unit. That design helps keep the belt stable on multi-groove drives. The KB series from Optibelt is built for drives where a single belt would not carry the load or track properly.
The 3124 mm length is the datum length for this belt. When checking a replacement, match both the profile and the length exactly. A belt that is too short or too long will not tension correctly and can damage sheaves or bearings. Confirm the length on the old belt before ordering.
To request a quote, send the part number B 120 KB and the quantity you need via WhatsApp or email. Our team replies promptly and can help confirm the right belt or suggest an equivalent if needed. We carry Optibelt belts and serve customers across the United States, Canada, Mexico and South America.
