Heavy Duty Conveyor Roller and Idler Structure

The structure of a conveyor roller typically consists of several key components designed to support and facilitate the movement of materials along the conveyor system. The structure of conveyor idlers is designed to support and guide the conveyor belt along its path, ensuring smooth and efficient material transport. MNSTACKER provides idlers and rollers for stacker conveyors and mobile shiploaders of bulk materials. We will talk about conveyor roller and idler structure in this article.

Conveyor Roller Structure

Roller Shell (Tube)

The roller shell, often cylindrical in shape, forms the outer surface of the roller. It provides support for the conveyor belt and facilitates its movement. Roller shells are typically made from materials such as steel, stainless steel, or plastic, depending on the application requirements.

Bearing Housing

The bearing housing is mounted inside the roller shell and houses the bearings. It provides a secure and stable mounting point for the bearings, ensuring smooth rotation of the roller. The bearing housing is often made from steel or cast iron and is designed to withstand heavy loads and harsh operating conditions.

Bearings

Bearings are installed within the bearing housing and provide rotational support for the roller. They reduce friction between the roller shaft and the roller shell, allowing the roller to spin freely as the conveyor belt moves. Bearings are typically made from materials such as steel or stainless steel and are chosen for their durability and reliability.

Roller Shaft

The shaft is the central rod that runs through the length of the roller and provides rotational support. It is securely attached to both ends of the roller shell and connects the roller to the conveyor frame. Shafts are usually made from steel and are designed to withstand bending and torsional forces.

Seals

Seals are used to protect the bearings from contaminants such as dust, moisture, and debris. They help to extend the lifespan of the bearings and ensure reliable performance of the roller over time. Seals are typically made from rubber or plastic and are designed to provide a tight and effective barrier against external elements.

End Caps

End caps are placed at each end of the roller to provide additional support and protection. They help to keep the bearings securely in place and prevent foreign objects from entering the roller assembly. End caps are often made from steel or plastic and are designed to withstand impact and abrasion.

Conveyor Idler Structure

Idler Roller

The structure of conveyor rollers is designed to withstand heavy loads, resist wear and tear, and ensure smooth and reliable operation of conveyor systems in various industries and applications. The HDPE roller and UHMWPE roller can decrease the weight of mobile conveyors and reduce requirements on ground conditions. Conveyor roller types:

Steel Roller
HDPE Roller
UHMWPE Roller
Rubber Disc Roller
Impact Roller

Idler Frame

The idler frame is the structural framework that supports the roller assembly and attaches it to the conveyor structure. It is typically made from steel and is designed to withstand the weight of the conveyor belt and the materials being transported.

Overall, the structure of conveyor idlers is designed to withstand heavy loads, resist wear and tear, and ensure smooth and reliable operation of conveyor systems in various industries and applications.
