Product Description:

The conveyor idler (or roller) is a core rotating component of belt conveyors, designed to support the conveyor belt and bulk materials, minimize running resistance, reduce belt wear, and ensure stable belt operation. As the most numerous and critical parts in conveyor systems, idlers account for approximately 35% of total conveyor cost and influence over 70% of operating resistance. Their quality directly determines conveyor efficiency, energy consumption, and service life (the belt itself represents over 25% of total cost).

Structure & Components

Idlers consist of four key parts, engineered for low friction, reliable sealing, and long life:

  • Roller Body: The cylindrical shell (seamless steel pipe, stainless steel, or polymer).
  • Shaft: A fixed, high-strength steel rod (the roller rotates around it).
  • Bearings: Precision ball/roller bearings (minimize rotational resistance).
  • Sealing System: Multi-layer labyrinth + rubber seals (block dust, water, and debris from bearings).
Main Types & Functions:

Idlers are classified by function, position, and design:

(1) Troughing (Carrying) Idlers
  • Structure: 3 rollers (1 horizontal center + 2 angled side rollers) forming a trough angle (20°, 35°, 45°).
  • Function: Support the loaded carry-side belt, contain bulk materials (prevent spillage), and distribute weight evenly.
  • Application: Standard for mining, coal, ports, and heavy bulk handling.
(2) Return Idlers
  • Structure: Single flat roller (sometimes with a slight crown).
  • Function: Support the empty return-side belt, prevent sagging, and maintain belt alignment.
  • Application: Installed below the conveyor frame, spaced 1.5–3m apart.
(3) Impact Idlers (Shock Absorbing)
  • Structure: Roller body with rubber/polyurethane rings (15–30mm thick) or buffer layers.
  • Function: Absorb heavy impact forces at loading points (where materials drop onto the belt), protecting the belt from tears and abrasion.
  • Application: Mining, quarrying, and high-drop loading zones (≤3m drop height).
(4) Self-Aligning (Training) Idlers
  • Structure: Troughing/parallel idlers with side guide rollers or a rotating frame.
  • Function: Automatically correct belt misalignment (a common issue causing edge wear).
  • Application: Long-distance, high-speed conveyors (ports, power plants).
(5) Transition Idlers
  • Structure: Gradually angled rollers (between troughing and flat sections).
  • Function: Smoothly transition the belt from flat (at pulleys) to troughed (carrying side), reducing belt stress and fatigue.

Key Performance Parameters:
  • Diameter: 89mm, 108mm, 133mm, 159mm (matches belt width: 500–2400mm).
  • Bearing Life: ≥50,000 hours (under rated load).
  • Rotational Resistance: ≤0.02N (low friction for energy savings).
  • Radial Runout: ≤0.5mm (prevents belt vibration).
  • Sealing Grade: IP65 (dust-tight, water-resistant).

Industrial Applications:
  • Mining & Coal: Ore, coal, and mineral transport (ISO 5048 standard).
  • Ports & Terminals: Grain, fertilizer, and container handling (JIS B8805).
  • Cement & Power Plants: Clinker, ash, and raw material conveyance (DIN 22101).
  • Food : Safe, corrosion-resistant material transport.
Packing and Shipping:

Each Conveyor Idler Roller is carefully packaged to ensure maximum protection during transit. The rollers are individually wrapped in protective materials to prevent scratches and damage. They are then securely placed in sturdy cardboard boxes with cushioning materials to absorb shocks and vibrations.

For bulk orders, the packaged rollers are stacked on pallets and wrapped with stretch film to maintain stability. All packages are clearly labeled with product information, handling instructions, and shipping details to facilitate smooth logistics.

We offer reliable shipping options that ensure timely delivery to your specified location. Our logistics partners handle the packages with care, and tracking information is provided for all shipments to keep you updated on the delivery status.
