Feature: 1. Application: The round belt is used in round belt transmission, and the round belt transmission generates friction force by pressing the belt and the wheel grooves, which has good elasticity. 2. Relieve Shock and Vibration: Relieve shock and vibration during the operation of the round belt, smooth movement and low noise. 3. Protecting Machinery: When the load is too large, the belt will slip, which can protect the machinery and motor. 4. Useful Round Belt Transmission: Round belt transmission is particularly useful in some low speed and low power transmission applications. 5. High Tensile Strength: The round belt has high tensile strength, abrasion resistance, abrasion resistance and impact resistance.
