Typical Applications
- CNC machine tool axes and rotary tables
- Robotic arm joints and end-effector drives
- Conveyor and indexing systems
- Packaging and labeling machinery
- Semiconductor and electronics assembly equipment
- Medical device positioning stages
System Compatibility
The NE23-020 is designed to mount directly onto NEMA 23 (57 mm) frame servo and stepper motors. Confirmed compatible motor families include:
- Parker SM232 / SM233 / SM234 Series
- Parker MPP Series (NEMA 23 frame)
- Parker BE Series (NEMA 23 frame)
- Third-party NEMA 23 motors with standard 4-bolt flange pattern
For non-standard motor shafts or flanges, an adapter plate may be required. Contact us for custom coupling solutions.
Selection Guide
Use the following criteria to confirm the NE23-020 is the right gearhead for your application:
- Motor frame: NEMA 23 (57 mm) ✔
- Required gear ratio: 20:1 ✔
- Backlash tolerance: ≤ 15 arcmin acceptable ✔
- Input speed: ≤ 4,000 RPM ✔
- Environment: Indoor / light industrial, -10 °C to +90 °C ✔
- Need lower backlash (< 5 arcmin)? → Consider Wittenstein alpha or Neugart PLFE series
- Need higher torque? → Step up to Parker NE34 series (NEMA 34 frame)
- Need a different ratio? → Parker NE23-005 (5:1), NE23-010 (10:1), NE23-050 (50:1)

Replacement & Compatibility FAQ
Q: Are P/N 54020146, 930Y2NO/NCFSFFMA, and 100016885 the same part?
A: Yes. These are all Parker internal part number variants for the NE23-020 gearhead. They are interchangeable.
Q: Can I use the NE23-020 with a non-Parker motor?
A: Yes, provided the motor has a standard NEMA 23 flange and a compatible shaft diameter. Verify the motor shaft length and keyway before ordering.
Q: What is the backlash of the NE23-020?
A: Typically ≤ 15 arcmin for the standard NE-Series. Contact us if you require a low-backlash variant.
Q: Is the Neugart PLE60-020 a direct drop-in replacement?
A: In most cases yes for NEMA 23 motors, but verify the output shaft diameter and bolt circle before installation.
Q: Do you offer warranty on replacement units?
A: Yes — 12-month warranty on all new OEM units. Refurbished units carry a 90-day warranty.
