1. Diameter: 89-219 mm.
2. Length: 190mm to 3500 mm.  Using the international standard design and manufacturing technology, our company improves the production and design of idlers to a higher level. The idler produced by our company enjoy minimum revolving resistance, long life, small maintaining work and high carrying capability. Idler is the main part of belt conveyor, our company adopts special fine welding steel pipe for idler, in order to reach the high-speed operation requirements. The bearing holder has been manufactured after stamping many times by the imported cold griped steel. Adopting the big roving crack bearing can greatly reduce the friction resistance. The sealing technology has been specially designed, filled with resisted high speed, high temperature and ultralow temperature antioxidant lithium. So it prevents the corrosion of the impurity, the water and the air effectively.At present, the idler series products include the carrying idler, the impact idler, the centering idler, the idler with rubber disc and the parallel idler, etc.
