• Large high-capacity bearings
• Increase Overhung Load
• Increased Hollow Bore Capacity
• FEM (Finite Element Modeling)
• High Strength Aluminum Housing
• Corrosion-Resistant
• NEMA, IEC or Solid Shaft Input As Standard
• Accommodates C-Face motors or brakemotors

Gearbox Selection

Below are some guideline steps to help aid in
the gear unit selection.
1. Determine the speed and/or gear ratio (see order form)
2. Determine the required power or torque (see order form)
3. Determine Service Factor 
4. Select the basic gearbox type and input
5. Determine the required mounting position
6. Select options
7. Checks – overhung load, thrust load, NEMA motor weight, thermal considerations, and other application considerations
