The purpose of a wear-resistant covering is twofold. The fabric provides wear resistance, making the triangle belt more durable. The contact between the belt and pulley is constant and can occur at very high speeds. This additional protection against contamination and wear on the belt and pulley allows the belt to operate longer before it wears out too much to properly transmit the required power. PRODUCT INTRODUCTION its principai part is made of oil proof and best heat resistance compound rubber,and the tramework is made of special polyester stiff cord. V-BELT PRODUCT FEATURES Large intensity, high flexibility, good durability; Special bottom rubber used, small elongation and long service life; Excellent heat-resistence, oil-proot, and wearing resistence; High transmission efficiency; Suitable for band pulley with minor diamenter; Safe performance can be guaranteed even during high-speed operation.
