Product Features
Wide Selection of Sizes
High quality and abundant variations are achieved through systematic component configuration. 26 sizes available, giving you the ability to select the best product for your needs.
High Strength Gears
Uses a 25° gear pressure angle for high dedendum strength. Gearmotor with a high load capacity, capable of withstanding strong impact loads.
Low Noise
In addition to proper gear tooth profile modification, it uses a high rigidity housing created through FEM analysis to minimize housing deformation under loads. This allows it to maintain good tooth contact, resulting in low noise.
Increased Thermal Capacity
Newly designed cooling fan and cover. As a result: a major increase in the thermal rating. There's power to spare, even under harsh environments and continuous operation.
Accommodates Various Mounting Directions
Housing structure can be mounted in any orientation: horizontal, vertical, or upright. It can accommodate all of your needs.
PARAMAX® Reducer in a Gearmotor Configuration
A hollow input shaft is used on right angle types. Direct motor coupling is now standard.

Frequently Asked Questions
Do you have questions about the Paramax® Drive? Below are some of our most commonly asked questions or you can view our Support area under Knowledge for more frequently asked questions and answers.
A gear tooth, such as that of Paramax, with a 25-degree pressure angle provides for greater torque transmission due to its wider dedendum. It is also important in minimizing tooth breakage due to shock loading.
Yes, 1.25:1 thru 5:1 in the parallel shaft configuration; and 1.6:1 thru 4:1 in the right angle shaft configuration.

Special voltage, dust-proof, humidity-proof, high-temp, special shaft, CSA and NEMA standard conformance options are available.
Yes, 1.25:1 thru 5:1 in the parallel shaft configuration; and 1.6:1 thru 4:1 in the right angle shaft configuration.
Yes, many options exist for integral backstop; consult the factory for design details.
Up to 5 million inch-pounds, or more than 550 kiloNewtons
Yes, but these are options, and require additional design lead time.
Please consult a Sumitomo Sales Representative. They will review your application and provide an optimum Paramax selection.
While all gearboxes maintain thermal limitations, our new Paramax 9000 series has been improved to provide an 87% higher thermal rating over the previous series. This results from optimizing the units' fan cooling system as well as the airflow over the surface.
