Non-metallic oil-free rollers are a new generation of high-tech industrial mining supply developed by our company that use plastics instead of steel. The technical advantages are:
a. The tube body is made of polymer composite material, which has the advantages of flame retardancy, high wear resistance, long life, non-magnetic, no adsorption of iron powder, dust and various sticky substances, low friction coefficient with the belt, self-lubricating, etc., which greatly avoids the defects of steel rollers and ceramic rollers, thereby greatly extending the service life of the belt and avoiding damage to the belt ;
b. The design of non-metal rollers fully considers the use environment and user needs. It adopts an embedded combination design, which enables the roller to maintain better stability when bearing loads. At the same time, the bearing seat of the non-metal roller is closely connected to the cylinder, with a large load-bearing capacity, avoiding the problem of separation and scratching the belt during work, and improving work efficiency. In addition, the bearing seat of the non-metal roller is made of special materials, which is non-heat-conductive and high-temperature resistant, further improving the performance and safety of the product.
The sealing structure adopts a double labyrinth design (after immersion test, the water inflow is almost zero) and precision assembly, which completely isolates the bearing from the outside world. It can effectively protect the bearing for long-term and continuous operation, and avoid dry grinding of the belt and roller skin caused by the bearing being contaminated and not rotating. At the same time, it replaces the traditional welding process, improves the concentricity, makes the equipment run more smoothly, and extends the service life of the roller.

d bearing is a fully sealed maintenance-free bearing specially used for rollers, which has the advantages of flexible operation, long life and maintenance-free.

a. During production and use, users can reduce the replacement frequency of rollers, save labor costs and other expenses, and reduce production stoppage losses;
b. The weight of non-metallic non-lubricating oil roller is only half of that of metal roller, which is convenient for transportation, reduces the labor intensity of workers and improves work efficiency;
c. After using the non-metallic oil-free rollers produced by our company, the total weight of the conveyor is reduced by more than 20%, and the operating current is reduced by 10%. Through several years of observation and records, the conveyor equipped with non-metallic oil-free rollers can save more than 10% of electricity compared with traditional metal rollers, which improves the economic benefits of the user unit.

a. In the food industry, non-metallic rollers meet hygiene requirements, are easy to clean, and are suitable for occasions with high environmental hygiene requirements ;
b. In the pharmaceutical industry, non-metallic rollers can keep clean, prevent cross contamination, and meet the pharmaceutical industry's demand for equipment cleanliness ;
c. In the electronics industry, non-metallic rollers have low operating noise, little impact on products and the environment, and are conducive to improving product quality ;
d. In the chemical industry, the anti-corrosion performance of non-metallic rollers can effectively cope with the erosion of corrosive substances and ensure the stable operation of equipment ;
In the mining production industry, the flame retardant, high wear resistance, and non-adsorption of impurities properties of non-metallic rollers can effectively improve belt transportation and reduce the risk of accidents.

Main function

The main function of non-metallic rollers is to support and transport materials. In the conveyor belt system, rollers are responsible for supporting the conveyor belt and keeping it running smoothly. With their excellent wear resistance and corrosion resistance, non-metallic rollers can ensure that the conveyor belt can still run stably in harsh environments and reduce the possibility of failure. At the same time, the lightweight design of non-metallic rollers also reduces the energy consumption of the entire system and improves energy efficiency.

Introduction to use

Applicable Industries

Non-metal rollers are widely used in a wide range of industries, covering almost all industrial fields that require material transmission. Non-metal rollers are widely used in industries such as coal, mining, electricity, chemicals, and building materials. These industries have extremely high requirements for conveyor belt systems, and non-metal rollers provide a strong guarantee for the production of these industries with their excellent performance.

Scope of Application

The application scope of non-metallic rollers is also very wide. Whether indoors or outdoors, whether in dry or humid environments, non-metallic rollers can play their excellent performance. Especially in some highly corrosive environments, non-metallic rollers can better reflect their corrosion resistance advantages and ensure the long-term stable operation of the conveyor belt system.

Precautions for Use

When using non-metallic rollers, you need to pay attention to the following points: First, ensure that the rollers are installed firmly and stably to avoid shaking or vibration during operation; second, the rollers should be inspected and maintained regularly to detect and deal with potential problems in a timely manner; finally, during transportation and storage, the rollers should be protected from impact and extrusion to avoid affecting their performance.
