Carlisle BX126 Gold Ribbon Cog-Belt is a one‑strand, BX‑section cogged V-belt with a 21/32 in top width and a nominal outside length of 129.0 in (129.3 in outside circumference). It is constructed from EPDM synthetic rubber with a polyester cord for enhanced heat resistance and durability. The Gold‑Ribbon Cog‑Belt design uses a precision cog profile and raw‑edge sidewalls to improve flexibility, reduce bending stress, and deliver smoother operation, with Carlisle noting up to 30% more horsepower in the same drive space and cooler running. Operating from -50°F to +250°F, made in the USA, the BX126 belt weighs about 1.64 lb and is intended for BX‑section pulleys and QD‑type (BQ) drives.
