Overview of Different Types of Conveyor Rollers

  1. Impact Rollers:
    Impact rollers are specifically designed to absorb shock loads during loading operations. They feature rubber rings or sleeves fitted around a steel core, which cushions the belt from heavy, sharp, or abrasive material impact. Impact rollers are often positioned at loading zones where materials are first deposited onto the conveyor system, ensuring that the belt remains undamaged while the load is cushioned.
  2. The rollers on return side (of conveyor belt) provide the support that is required for the return as well as to keep the belt from sagging and preventing the belt from being slack. The rollers have spacers that prevent the material from accumulating on the belt.  They can be either flat, grooved or V-shaped to keep the belt in place. The directly options are maintenance of their proper working condition which will prevent belt slippage or misalignment, which in turn, will result in conveyor system downtime or repairs that will be expensive.
  3. Mini Rollers:
    Mini rollers, or small-diameter rollers, are designed for lightweight material handling in compact spaces. Their reduced size is ideal for tight transfers between conveyors and systems where precision handling is crucial. They are often used in industries like pharmaceuticals, food processing, and electronics, where smaller, delicate, or lightweight products are transported and controlled.
  4. Steel Rollers:
    Steel rollers are versatile and durable, making them suitable for heavy-duty applications like mining, bulk material transport, and quarrying. Their high load-bearing capacity ensures that heavy materials are transported efficiently without compromising roller longevity. Steel rollers are often galvanized or coated to provide corrosion resistance in harsh environments.
  5. Nylon Rollers:
    Nylon rollers are lightweight, corrosion-resistant, and provide excellent resistance to wear. They are used for material handling applications requiring quieter operations or in environments where static buildup must be minimized. Nylon rollers are ideal for conveying small, lightweight products or where high-speed movement is necessary.
