Product Description

Parallel Carrying roller:
I. Structural characteristics

1. Regular shape: Usually in the shape of a cylinder, with a simple structure that is easy to install and maintain.
2. High-precision manufacturing: The diameter and length of the roller of the idler are relatively accurate, ensuring stability and reliability during the conveying process.

II. Performance characteristics
 

1. Strong carrying capacity: Can bear a large weight of materials and conveyor belt tension, suitable for various heavy-duty conveying equipment.
2. Stable operation: Due to the smooth surface of the roller and good contact with the conveyor belt, it can ensure that the conveyor belt runs smoothly without jitter during operation, reducing material spillage and equipment wear.
3. Low friction coefficient: The friction coefficient between the idler and the conveyor belt is small, reducing the running resistance, reducing power consumption, and improving conveying efficiency.
4. Good sealing performance: Adopting high-quality seals effectively prevents impurities such as dust and moisture from entering the inside of the idler and prolongs the service life of the idler.

III. Characteristics of application scope
 

1. Widely used: Applicable to various belt conveyors in industries such as coal, mines, ports, power, and metallurgy.
2. Adapt to different environments: Can operate stably for a long time in harsh working environments such as high temperature, high humidity, and dusty environments.

The parallel carrying idler mainly has the following characteristics:

In terms of structure and installation
 

• Simple structure: Usually composed of basic components such as rollers, bearings, shafts, and brackets. There is no complicated mechanical structure, which is easy to manufacture and maintain.
• Convenient installation: Its design is highly standardized. During the installation process of the conveyor system, it can be installed and debugged quickly and conveniently, effectively saving installation time and labor costs.

In terms of operating performance
 

• Stable operation: The parallel design enables the idler to maintain a stable state during operation and provide uniform supporting force for the conveyor belt. This can reduce the jitter and deviation of the conveyor belt, ensure the smooth transportation of materials during the conveying process, and reduce the risk of material spillage.
• Low noise: During operation, the coordination between various components is relatively good, and the friction and vibration generated are relatively small, thereby reducing operating noise and helping to improve the working environment.

In terms of carrying capacity and adaptability
 

• Moderate carrying capacity: Can bear a certain weight of conveyor belt and material load. In conventional material conveying scenarios, such as the conveying of bulk materials (such as coal, ore, grain, etc.), it can meet the needs of most medium-load conveyings.
• Strong adaptability: Suitable for multiple types of conveyor belts. Whether it is an ordinary fabric conveyor belt or a rubber conveyor belt, it can work well with it. And under different working environment temperature and humidity conditions, as long as it is within a reasonable range, it can maintain normal working performance.

In terms of maintenance and cost
 

• Low maintenance cost: Due to the simple structure, the parts are easy to replace. In daily maintenance, it mainly involves work such as lubricating the bearings, cleaning the surface of the roller, and checking whether the parts are damaged. These maintenance works are relatively simple and do not require special tools and complex technologies, which can effectively reduce maintenance costs.
