At the heart of the Cyclo Drive is the unique Cycloidal disc mechanism. Unlike traditional gears, the Cycloidal disc mechanism provides a smooth, rolling motion, reducing wear and ensuring consistent performance over an extended lifespan. This makes Cyclo Drives particularly well-suited for demanding applications in heavy industries such as mining, construction, and material handling.

The versatility of Cyclo Drive technology is evident in its application across various industries. In conveyor systems, for instance, Cyclo Drives offer precise control over speed and torque, contributing to the overall efficiency of material handling processes. The ability to handle high shock loads also makes Cyclo Drives indispensable in applications where equipment durability is paramount.

Paramax® Gearmotor Technology

Sumitomo’s commitment to delivering comprehensive solutions is exemplified by its Paramax® Gearmotor technology. Developed to address the increasing demand for high-performance gearmotors, Paramax® combines the advantages of gear technology with the efficiency of integrated motors.

The Paramax® Gearmotor is designed for heavy-duty applications that require reliable and energy-efficient solutions. Its compact and modular design allows for easy integration into various industrial systems, making it an ideal choice for industries such as mining, pulp and paper, and water treatment.

One of the key features of Paramax® Gearmotors is their high torque density. This means that they can deliver significant power in a compact form factor, allowing for more flexible and space-efficient system designs. Additionally, Paramax® Gearmotors are engineered for low maintenance, reducing downtime and operational costs.

Hypoid Gear Technology

Sumitomo’s commitment to innovation extends to its hypoid gear technology, which is a type of spiral bevel gear that provides enhanced performance in terms of efficiency, durability, and noise reduction. Hypoid gears are widely used in automotive applications, but Sumitomo has successfully adapted and expanded their use in various industrial settings.

The unique geometry of hypoid gears allows for a high level of torque transmission efficiency while minimizing noise and vibration. This makes them ideal for applications where smooth and quiet operation is crucial, such as in conveyors, mixers, and packaging machinery.

In addition to their efficiency and quiet operation, hypoid gears from Sumitomo are designed for durability. The advanced materials and precision engineering employed in their manufacturing ensure a long service life, even in demanding environments. This durability is particularly valuable in industries where equipment reliability is paramount, such as in food and beverage processing and pharmaceutical manufacturing.
