roller group

The roller group is comprised of roller and frame, which is the main parts of the belt conveyor. The rollers/idlers are made from high precision welding pipes and seamless tubes, steel plates and the body of the roller/idler and the bearing are welded as an integrated one by extrusion and argon guarantee welding, which make the rollers/idlers low resistance coefficient, long lifetime. The seal of our rollers/idlers are labyrinth seal, which make the rollers/idlers fine waterproof and dustproof. The concentric design of the roller/idler decreases vibration. Roller frame are designed to provide a minimum gap between rollers, and give added protection to the conveyor belt. Frame outer slopers are designed to prevent material build up around the shell end thereby avoiding premature shell wear due to roll jamming. Base frame cross members are designed for optimum strength weight ratio whilst providing adequate support the roller under load conditions. All frames are inspected prior to commencing the welding run to confirm accuracy of major dimensions. Selected frames are removed from the productions run at intervals and subjected to full dimension checks and weld quality inspection. Besides we can manufacture the rollers and idlers according to the buyers' requirements
