Motorized Pulleys 500H

Motorized pulleys 500H are designed to meet the most demanding requirements within the bulk handling conveyor market. They are specifically engineered for applications where belt conveyors require exceptionally large pulley diameters to ensure efficient, stable and reliable power transmission over time.

Thanks to their advanced design and robust construction, the 500H series delivers consistent performance even in environments characterized by high dust levels, variable loads, continuous operation, and frequent start-stop cycles. These conditions require equipment capable of withstanding heavy mechanical stress without compromising efficiency or reliability.

The high torque capacity and durable structure of the Rulmeca 500H model make it ideally suited for handling heavy loads while maintaining smooth and efficient conveyor operation. In addition, the compact and fully sealed design protects internal components from contamination, reducing wear and extending service life.

This model represents a reliable and low-maintenance drive solution for tough and irregular applications. Its compact design allows easy integration into conveyor systems while optimizing space and simplifying installation.

To ensure optimal performance, it is essential to accurately calculate the belt tension (T1+T2), as this determines the torque and power required to operate efficiently. If the estimated belt tension exceeds the maximum permissible radial load, or if heavy or large belts are used — resulting in increased tension — alternative series may be required. Selecting the correct drive solution is crucial to guarantee safe, efficient and reliable conveyor operation.

H means Heavy-duty motorized pulleys

The 500H model represents the heavy-duty range, specifically designed to withstand the most demanding application requirements. Its mechanical strength and durability define every aspect of its construction, ensuring long-lasting performance even under extreme operating conditions.

All internal components — including the gearbox and bearings — are engineered for maximum strength and efficiency, allowing reliable operation even in irregular and heavy-duty environments. This robust construction ensures continuous, trouble-free service where conventional drive systems may fail.

As a result, the 500H combines high mechanical efficiency, minimal maintenance, and superior environmental protection within a single sealed unit. It offers a powerful, space-saving and highly reliable solution for the most challenging bulk-handling applications.
