1. Product Description

The idler is a critical component of belt conveyor systems, supporting the conveyor belt and transported materials to ensure smooth and efficient operation. Our idlers are designed for long service life, high load capacity, and reliable performance under various working conditions.

Manufactured with precision processes, they are available in both press and welded types to suit different application environments. Whether used indoors or outdoors, in extreme heat or cold, our idlers deliver consistent performance with low noise and excellent sealing protection.

2. Product Type

We offer two main types of idlers to meet diverse application needs:

1. Pressed Type Idler: Formed by pressing the bearing housing into the tube, providing good concentricity and suitable for general industrial applications.

2. Welded Type Idler: Bearing housings are welded to the tube, offering higher structural strength and stability, ideal for heavy-duty and harsh working conditions.

Both types can be customized in terms of tube diameter, wall thickness, and shaft size to meet specific customer requirements.

3.Technical Data

4.Main Functions of Steel Roller:

1. Support and Guidance: Supports the conveyor belt and material load, maintaining belt alignment and reducing deflection.

2. Friction Reduction: Minimizes rolling resistance, lowering energy consumption and extending belt life.

3. Sealing Protection: Multi-layer labyrinth and contact seals effectively prevent dust and moisture ingress, ensuring long-term reliability.

    

5.Applications:

Our idlers are widely used in various industries and environments:

• Mining and quarrying

• Steel and cement plants

• Port handling and terminals

• Coal and power generation

• Chemical and fertilizer industries

• Grain and bulk material storage

• Long-distance belt conveyor systems

• Extreme climate regions (high temperature, low temperature, high humidity, or dusty conditions)

6.Quality Control & Testing

All idlers undergo strict quality control throughout the production process:

Raw Material Inspection: Shaft steel, tubes, bearings, and seals are inspected upon incoming.

Dimensional Accuracy: Tube concentricity, shaft straightness, and assembly tolerances are measured with precision instruments.

Sealing Performance Test: Each idler is tested for dust and water ingress protection.

Running Resistance Test: Rotational resistance is measured to ensure energy efficiency.

Noise Test: Operating noise is controlled within ≤42 dB.

Dynamic Load Test: Selected samples undergo dynamic load testing to verify service life.

Paint Adhesion Test: Polished surface and paint process ensure long-lasting corrosion protection.
