Precision Conveyor Rollers

Conveyor Idlers Manufacturer

Efficient material handling systems depend on durable, low-friction conveyor idlers. We manufacture heavy-duty conveyor belt idlers engineered for reliable belt support, smooth operation and long service life.

Our industrial conveyor idlers are used in mining, cement plants, steel manufacturing, ports, power plants, bulk material handling facilities and conveyor infrastructure projects.

What Are Conveyor Idlers?

Conveyor idlers are cylindrical rollers installed along a conveyor frame to support and guide the conveyor belt during material transportation. They reduce friction, maintain belt alignment and distribute load evenly across the conveyor system.

  • Support belt and conveyed material load
  • Reduce conveyor belt wear
  • Ensure smooth belt travel
  • Prevent belt misalignment
  • Minimize operational downtime
  • Improve system efficiency and belt life

Types of Conveyor Idlers We Manufacture

We manufacture a complete range of conveyor idlers for different load capacities, belt widths, trough angles and operating environments.

Carrier idlers for conveyor belt load support

Carrier Idlers

Carrier idlers support the loaded belt, commonly using trough arrangements with 20, 30 or 45 degree angles for bulk material handling.

Return idlers for empty conveyor belt support

Return Idlers

Return idlers support the empty belt on the return side, reducing belt sagging and helping maintain smooth conveyor operation.

Impact idlers for conveyor loading zone

Impact Idlers

Impact idlers use rubber cushioning to absorb shock at loading zones and protect conveyor belts from material impact damage.

Self-aligning conveyor idlers for belt tracking

Self-Aligning Idlers

Self-aligning idlers correct belt tracking, reduce spillage and improve conveyor efficiency where misalignment risk is high.
