We can manufacture the rollers/idlers of dia 50-219mm length 190-3500mm, which are used in the steel industry, harbor, coal industry, power industry, cement industry, etc and we have Passed CE certification and ISO9001:2000 certificate.
The rollers/idlers are made from high precision welding pipes and seamless tubes, steel plates and the body of the roller/idler.
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.
Our conveyor rollers have been exported to more than 70 countries all over the world in past 44 years and we have professional engineers and all of them have rich experience in this field, we can design the goods independently
