A B C D E Z series Common Rubber V belt
Structure & Characteristic
Structure & CharacteristicOur Rubber V belt is making from specially-selected high-quality rubber materials and reinforcement with low elongation by sophisticated technological formula, and fits the international advanced standards with strict quality management.
The company improves product quality in the spirit of continuous research, development and creation, making products have advantages of high wearing resistance, low elongation and long life.
Structure
Wrapping Cloth: Select special cotton canvas, with high tensile resistance, good wearing resistance and strong resistance of belt surface.
Buffered Rubber: Select rubber with high resistance and wearing resistance, and low compression and deformation to hold the normal section shape of the belt in the case of use and protect bodies at the center of the rubber belt.
Elongation resistant Body (Reinforcement): Select polyester ropes with extremely strong tension and non elongation as the main part of rubber belt strength.
