Browning BX79 Gripnotch V-Belt

The Browning BX79 Gripnotch V-Belt is a BX-series cogged belt designed for rugged, long-life power transmission in industrial equipment and HVACR systems. It features a 21/32-inch (0.65625") top width, a single strand construction, and 82 inches of outside circumference, fitting BX drive configurations that call for a notched, high-efficiency belt. Built with EPDM compound, the BX79 delivers a wide operating temperature range from -60°F to 250°F, helping resist heat-induced wear in demanding environments. The Gripnotch (notched) form reduces belt slip and heat buildup compared with wrap belts, extending service life when replacing existing belts in aligned BX pulleys. The belt thickness is approximately 0.41 inches, and the BX79 is a common choice when upgrading to a cogged profile to improve load-carrying capacity and efficiency in industrial motors and fans. This belt is typically used in machinery and HVAC equipment where a reliable, precisely profiled belt is required, and it is designed to meet the needs of BX-section drive systems across a range of temperatures and duty cycles.
