Are there drop bearing designs?
Yes.
What advantage does tooth form have on ratings?
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.
What are service factors and how are they used?
In general, reducers and gearmotors are rated for specific conditions and operating requirements of the application by the use of AGMA-defined Service Factors. There are three AGMA load classifications for reducers: uniform (U), moderate shock (M) and heavy shock (H), and three AGMA load classifications for gearmotors: I, II, and III. Refer to our catalog for a list of AGMA load classifications. These Service Factors are used in the product selection process to adjust for the specific conditions and operating requirements of your application.
Are there single stage ratios available for Paramax®?
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.
Are there drop bearing designs?
Yes.
What type of special motors can I order with my Paramax?
Special voltage, dust-proof, humidity-proof, high-temp, special shaft, CSA and NEMA standard conformance options are available.

What are some of the thermal limitations of Paramax?
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.
How can I be sure that a Paramax is right for my application?
Please consult a Sumitomo Sales Representative. They will review your application and provide an optimum Paramax selection.
Can I order ductile iron or fabricated steel housing for Paramax?
Yes, but these are options, and require additional design lead time.
