"PHA" Series – Inline ServoFit Gearhead "PH" Series
The "PHA" Series is well suited where a smooth, precise, reliable drive is needed. The FlexiAdapt™ motor coupling is designed for accurate and precise motor installation. The integrated thermal expansion feature, in the shape of a bellows, compensates for linear thermal expansion of the motor shaft. Adapter bushings are provided when needed to fit any motor shaft.

Standard Features
- Ground and honed gearing provides smooth running.
- Balanced clamp coupling for smooth operation at high speeds.
- The addition of binary ratios, 8, 16, and 32:1, simplifies control systems.
- Precision selection of parts ensure optimal performance without binding gear teeth, resulting in a more accurate and smooth direct drive.
Benefits
- Readily attaches to any servo motor
- Backlash – 1 arc minute or less – is the result of high quality gear manufacturing, not preloading during assembly. This eliminates cogging velocity ripple and collisions that cause backlash growth.
- Superior Torsional Stiffness
- 90-96% Efficiency
- Assembled in the U.S.A.
- 5 Year Limited Warranty (2 years on bearings, seals, etc.)
- A bellows style input coupling compensates for linear thermal expansion of the servo motor shaft by absorbing shaft length growth which normally causes a change in gear position. This compensation eliminates positioning errors enabling your machine to perform the same regardless of hot or cold temperature.
