1、The closed loop belt has high tensile strength, elongation, reversible crystallinity, and good adhesion. 2、Timing belts are resistant to oil, second only to nitrile rubber, heat resistance, performance equivalent to nitrile rubber, flame resistance, certain flame retardancy, ozone resistance, and excellent chemical resistance. 3、The neoprene arc toothed synchronous belt has the advantages of low transmission sound and high efficiency. 4、5412 series neoprene arc tooth synchronous belts are used in conjunctionwith 5mmHTD synchronous pulleys to provide stable and reliable power transmission for the robot. 5、Compared with our 3mm neoprene arc tooth timing belt, the thicker pitchof the timing belt can handle larger loads without slipping or jumping teeth. 2 x Synchronous Belt Item Type: Closed Loop RubberMaterial: NeoprenePurpose: Mainly Used for Exactness Transmission, Such as Driving Shafts on for 3D Printers, Belt Pulley Transmission Between Mechanical Arms, etc.
