Polyurethane GUFERO® wedge shaped belts are designed in particular for compact drives with short distance between axes and small diameters of wedge shaped belt pulleys. Among characteristic properties of polyurethane wedge shaped belts are smooth running up to a speed of approx. 90 m/s and a very low noise level. The polyurethane mixture for wedge shaped 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 wedge shaped belts withstand temperatures up to +90 °C.
