Design Essentials of Flexible Structure Pulleys On account of bending moment and torque produced from the running of pulleys, especially the alternant fluctuant loads acting on pulleys, the composition of force put on pulles is very complicated. Therefore, the fatigue intensity must be accurately calculated during the process of design. Type Selection Scopes of Flexible Structure Pulley Description Specification Belt Width 500 - 3000 mm Pulley Diametre Dia.250 -2000mm Shaft Diametre at the location of Bearing Dia.40 - 500 Bearing Housing SKF, FAG, NSK and domestic brand products based on the requirement of our customer. Lagging Physical Property of Flexible Structure Pulleys Lagging of pulleys employ cold-vulcanizing rubber splicing of TIP TOP Company in German, the raw material and production technic are entirely from German. The lagging is of the property of wearable, good ant-aging,high splicing intenstity, steady hardness, good elasicity and large frictionfactor etc., the surface of it has better function of self-clearing.
