Return Idlers

Return idlers are essential components in conveyor belt systems. Their primary role is to support the lower side of the conveyor belt, assisting it in returning smoothly to the starting point after completing the material transport. Return idlers effectively prevent the conveyor belt from sagging, stretching, and misaligning, reducing downtime and maintenance costs caused by idler failures. Zoomry manufactures a range of return idlers specifically designed for the return section of the conveyor belt. Depending on the system's requirements, we offer flat return idlers, V-type return idlers, and rubber-disc return idlers, ensuring that various working environments and transport needs are met, guaranteeing the smooth operation of the conveyor belt during material transport.

■ Application Scenarios

Return idlers are widely used in various conveyor belt systems, especially in industries such as mining, steel, coal, power, fertilizer, grain, and chemicals. They support the return section of the conveyor belt, ensuring the smooth operation of the conveyor system and preventing damage or material wastage caused by sagging or misalignment. 

In high-load, high-capacity conveyor systems, flat return idlers, V-type return idlers, and rubber-disc return idlers can adapt to different transport conditions, helping to maintain proper tension and a stable operating trajectory of the conveyor belt, reducing equipment wear and extending service life. 

Return idlers are also commonly used in large conveyors and systems with complex paths, especially those that require high precision alignment and fine adjustment. They ensure the correct alignment of the conveyor belt, preventing tracking deviations and material spillage, thus ensuring operational efficiency and safety.

■ Product Features

● High Load Capacity: Zoomry return idlers are made of high-strength steel or stainless steel materials, capable of withstanding heavy loads and working reliably in harsh environments, ensuring efficient operation of the conveyor belt system.

● Strong Wear Resistance: All return idlers feature advanced sealing designs that effectively reduce friction and wear, extending the service life of the idlers.

● Multiple Configuration Options: We offer flat return idlers, V-type return idlers, and rubber-disc return idlers, allowing selection based on the specific conveyor belt design and operational requirements.

● Reduced Maintenance Costs: The simple design of return idlers results in lower maintenance costs, reducing system downtime and improving production efficiency.

● Prevention of Belt Misalignment: Return idlers ensure precise alignment and adjustment, effectively preventing the conveyor belt from misaligning, thus ensuring system stability and accuracy.

■ Product Types

● Flat Return Idler

The flat return idler is the most common type of return idler, primarily used to support the lower side of the conveyor belt and prevent sagging or deformation. Due to its simple and durable design, it is widely used in standard conveyor systems.

● V-type Return Idler

The V-type return idler consists of two idler rolls arranged in a V-shape, suitable for high-load and high-precision conveyor systems. V-type idlers provide better belt alignment, preventing material waste and equipment damage caused by misalignment.

● Rubber-Disc Return Idler

Rubber-disc return idlers have a self-cleaning function, effectively preventing material from sticking to the conveyor belt, reducing wear on the system. These are particularly useful in environments where wet or sticky materials are conveyed.

● Self-aligning Return Idler

Self-aligning return idlers feature an automatic adjustment function to ensure that the conveyor belt remains properly aligned during its return trip. The rotation of the central shaft and the guidance of edge rollers ensure that the belt does not misalign, preventing equipment failure and material loss due to tracking deviation.
