The Raw Edged Cogged Belts have two cut surfaces on both sides, so its resistance to bending and heat dissipation are better than wrapped belts. Short fibers are mixed in the rubber in the direction of the belt's width, contributing to power transmission and helping to resist abrasion caused by side pressure. Application: Used on heavy duty, high speed drives Main Type: FMX, AX, BX, CX, 3VX, 5VX, XPZ, XPA, XPB and XPC
