PH Series

Ideal for precision servo applications, the PH Series ServoFit® Precision Gearhead is designed for applications requiring high torsional stiffness and tilting rigidity. This inline unit has a flange output and short motor adapter length for easy and secure motor mounting. The PH series speed reducer has a backlash of ≤3 arcmin and readily attaches to any servo motor.

• Ratios – 4:1 to 121:1
• Backlash – < 1 arc/mins
• 90-96% Efficient
• Input Speed to 8000 RPM
• Noise Level – as low as 61 dB(A)
• Output Torque up to 44,290 in.lbs
• Flange Output,Tapered Roller Bearings for High Load Ratings

When starting a new motion control project involving a gearhead, In-Position Technologies engineers start by reviewing the key requirements to determine the optimum gearhead type, gear ratio, and form factor for the job. They perform all necessary engineering calculations to make sure the system performs as required, within customer specification, and without unnecessary cost. They will also recommend the appropriate accessories that will best fit the application.  

To ensure a gearhead fits the customer’s requirements, In-Position Technologies engineers review:

• Gear Ratio
• Gear Geometry
• Backlash
• Efficiency
• Weight
• Maximum Input RPM
• Nominal Output Torque
• Maximum Acceleration Output Torque
• Emergency Stop Torque
• Axial Load
• Radial Load
• Gearhead inertia at input
• IP Rating

When ordering the PH Series gearheads as a part of a full system, IP Tech engineers review the solution to ensure:

• All parts and accessories necessary for a complete working solution are included
• All components have been checked and verified to work together as a system
• The selected components will perform as required by the project specifications
