Hexagonal-section GUFERO® timing belts also known as double-sided timing belts, atypical timing belts, non-standard timing belts, double timing belts, etc. These timing belts are used in more complex drives with multiple timing belt pulleys where it is necessary to change the direction of rotation. Double timing belts are used for special applications in industrial equipment. The main advantages of hexagonal timing belts definitely include their long service life and low maintenance costs. The temperature resistance of double timing belts is from -40 °C to +70 °C.
