Our ZEDEX pulleys/sheaves protect ropes from increased frictional wear. The unique sliding surface of our material ensures that the friction between rope and pulley is reduced to a minimum. Thanks to their high mechanical strength and elasticity, the rollers withstand high loads and do not break. The high wear resistance and resistance to weather influences ensure a long service life. For example, our pulleys can be used for elevators, fitness equipment, boats and construction machinery.
