Product Introduction
Return idler is a roller product used to support the unloaded belt (return section) in the belt conveyor. It is usually installed at the bottom of the conveyor to ensure the smooth operation of the belt. The return idler is made of high-hardness steel or rubber coating, which can resist belt friction and material residue wear. Some models are equipped with automatic self-aligning functions (such as V-shaped or conical structures), which can effectively prevent the belt from running off and reduce maintenance requirements. At the same time, the precision bearing and seal design can reduce operating noise, which is suitable for indoor or environmentally friendly scenes.
Common types of return idlers include: flat return rollers, spiral return rollers, self-aligning return rollers, and buffer return rollers;
Regular colors:
Carbon steel is generally natural metallic silver-gray; galvanized rollers are generally bright silver and have strong corrosion resistance. Rubber coating is generally black (natural rubber) or green (wear-resistant synthetic rubber). Stainless steel rollers are generally matte stainless steel original color.
Manufacturing process:
In terms of steel pipe selection, return idlers generally use high-frequency welded pipes or seamless steel pipes to ensure roundness and strength; the surface is treated with polishing, galvanizing, plastic spraying or rubber coating to improve wear resistance and rust resistance. The sealing technology uses labyrinth seals + lithium-based grease lubrication, which can prevent dust and water, and in welding, laser positioning welding is used to ensure the concentricity of the bearing seat and the roller and reduce vibration.
Product Features & Applications
The return idler is mainly made of high-quality carbon steel, manganese steel or rubber-coated material, with high strength and wear resistance. It also has anti-slip design, self-cleaning function and corrosion resistance. It is galvanized, stainless steel or specially coated, and can also adapt to humid, dusty or corrosive environments (such as ports, chemical plants, etc.)
The return idler is widely used in mining and quarrying, and can effectively handle various minerals and rock materials. In the port and logistics industry, its anti-corrosion design enables it to adapt to humid and salt spray environments, ensuring long-term stable operation of the equipment under harsh conditions. In the field of cement and building materials, the spiral roller design of the return idler can effectively prevent the adhesion of powder materials and keep the belt clean, thereby improving production efficiency and reducing maintenance costs. In addition, it also plays an important role in the power and metallurgical industries, agriculture and other fields.
