Polyurethane GUFERO® engine belts are designed in particular for compact drives with short distance between axes and small diameters of engine belt pulleys. Among characteristic properties of polyurethane engine belts are smooth running up to a speed of approx. 90 m/s and a very low noise level. The polyurethane mixture for engine belts with a high friction coefficient ensures high efficiency resistant to ozone and most chemical substances and excellent resistance to the effects of oils and heat. Polyurethane engine belts withstand temperatures up to +90 °C.
