Product Introduction
The Carry Idler is a vital component in belt conveyor systems, responsible for supporting the upper belt and the load being conveyed. Built for durability, stability, and low-friction rotation, carry idlers reduce belt sag and contribute to extended service life of the conveyor belt. They are essential in applications involving bulk materials such as mining, aggregates, cement, ports, and industrial processing.
Types of Carry Idler
Trough Carry Idler (3-Roller)
The most common type, with a center horizontal roller and two angled side rollers (typically 20°–45°) forming a trough to cradle bulk materials.
V-Type Carry Idler (2-Roller)
Consists of two rollers in a V-shape, ideal for lighter materials or transitional conveyor zones.
Flat Carry Idler (1-Roller)
A single horizontal roller, used for flat belt applications or for conveying packaged goods.
Self-Aligning Carry Idler
Designed to automatically correct belt misalignment, ensuring stable operation and reducing wear.
Key Features
- High-load capacity and excellent impact resistance.
- Low rotational resistance, energy-saving design.
- Sealed bearing housing to prevent dust and moisture intrusion.
- Corrosion-resistant surface treatment (painted, powder-coated, or galvanized).
- Deep formed channel side brackets for extra strength.
- Non-clogging center stands.
- Heavy duty foot pads made for bolt mounting.
- Low noise and vibration during operation.
- Available in customized sizes, angles, and mounting styles.
