Spiral roller

Idlers are important components of belt conveyors. They support the conveyor belt and the material being conveyed, reducing the running resistance of the conveyor belt and ensuring that the conveyor belt sag does not exceed the specified limit, thus guaranteeing smooth operation. Their structure consists of a roller body, bearings, seals, etc. According to their use, they are divided into trough, parallel, and self-aligning types, and are widely used in mining, ports, power plants, and other fields.
