Description
Megadyne BX78 Cogged V-Belt, BX Section
The Megadyne BX78 is a raw-edge, molded-notch (cogged) V-belt in the BX cross section with a 80.7" outside circumference. The cogged profile flexes around small sheaves, runs at higher speeds, and sheds heat better than a wrapped belt. It is a direct replacement for Jason Industrial BX78.
