Superior’s Mine Duty Idlers provide improved performance for some of the highest capacity bulk handling applications. The new double tube (DT) design features inner and outer tube construction giving the idler increased rigidity for higher load ratings. This design has a 20% higher load rating than CEMA, which improves service life. The inner tube insulates the bearing from vibration, reducing misalignment and increasing the life of the bearing. As the outer shelf wears, the inner tube maintains the structural integrity of the roller. The double tube models are available in belt widths up to 120 inches and are equipped with bearing sizes up to 60mm. The DX Idler is designed with a 30mm bearing and ¼ inch thick wall for added durability, specs that are unrivaled in the market.
