Optibelt RR round section belts are made from high quality polyurethane using a special manufacturing process. They are produced as open-ended belts in various diameters and are available by the metre. The optibelt RR Plus version incorporates a polyester tension cord. The round section belts with tension cords are particularly low-stretch are therefore especially useful where longer transport distances need to be covered.Profile :Diameters from 2 to 20 mm
