INDUSTRY COMPONENT

Idler Roller

An idler roller is a cylindrical component that supports and guides conveyor belts without providing driving power, reducing friction and maintaining belt alignment.

Component Specifications

Definition
An idler roller is a non-powered cylindrical component used in conveyor systems, specifically within feed roller assemblies, to support the conveyor belt and its load. It rotates freely on bearings to minimize friction between the belt and the frame, ensuring smooth belt movement and proper tracking. Idler rollers are critical for maintaining belt tension, alignment, and stability in industrial machinery, preventing belt sag and reducing wear.
Working Principle
The idler roller operates on the principle of free rotation, where it supports the conveyor belt and reduces friction by allowing the belt to glide over its surface. It helps distribute the load evenly, maintains belt alignment through its positioning, and prevents belt slippage or misalignment by providing consistent support along the conveyor path.
Materials
Typically made from steel (e.g., carbon steel or stainless steel) for durability, with rubber or polyurethane coatings to reduce noise and wear. Bearings are usually sealed ball bearings for smooth rotation and low maintenance.
Technical Parameters
  • Length 200-2000 mm
  • Diameter 50-200 mm
  • Bearing Type Sealed ball bearings
  • Load Capacity Up to 500 kg
  • Rotation Speed Up to 100 rpm
Standards
ISO 1537, DIN 22101
