"Wrapped" means that the V-Belt core is protected by cover fabric made of cotton or polyester. The cover fabric is coated with rubber to reinforce the wear resistance.
Raw Edge V-Belts
Raw Edge V-Belts have no fabric on the belt sides. The special rubber compound ensures greater wear resistance than Wrapped V-Belts.
Cover cloth: It is highly elastic, can easily bend and stretch while the belt is rotating, and has strong resistance to wear.
Core line: Belt is the central part of strong power transmission. In order to fully satisfy this role, we use a core wire with high tensile strength, low elongation, and high bending fatigue resistance.
V-core rubber: Uses a highly flexible compounded rubber that is less deformed under high load and has excellent durability.
