Why Engineers Specify This Model
- Zero Backlash – Harmonic Drive strain-wave gearing eliminates backlash, delivering arc-second positional accuracy critical for servo-driven joints
- High Torque Density – Compact 025-size housing achieves torque output far exceeding conventional planetary gearboxes of equivalent volume
- Multi-SKU Cross-Reference – PGM-320REC, BM23951L29, BM17180L14/N, and EPS31196 are all validated cross-references, simplifying MRO procurement and BOM alignment
- Long Service Life – Precision-ground bearing races and controlled preload extend MTBF in continuous-duty servo applications
- Drop-In Replacement – Dimensional compatibility with HDA-025 series housings enables direct swap without mechanical redesign
- Stiffness & Damping – Integrated bearing assembly provides high torsional stiffness, reducing settling time in closed-loop servo systems

Application-Specific FAQ
Q: Is HDA-025-080-2-SP2222 compatible with FANUC R-2000iC robot joints?
A: The HDA-025 series is widely used in robot joint actuators of equivalent torque class. Verify mounting bolt pattern and output flange interface against your robot’s mechanical drawings before installation.
Q: What is the difference between HDA-025-080-2-SP2222 and a standard HDA-025-080-2?
A: The SP2222 suffix denotes a special specification variant — typically involving modified preload, sealing, or surface treatment. Consult the OEM datasheet or contact us for the specific SP2222 deviation sheet.
Q: Can this bearing assembly be used in cleanroom (ISO Class 5) environments?
A: Standard HDA bearing assemblies are not rated for cleanroom use without modification. Harmonic Drive offers cleanroom-compatible variants with special seals and low-outgassing grease. Contact us to confirm suitability.
Q: What is the expected service life under continuous duty?
A: Under rated load and proper lubrication intervals, Harmonic Drive bearing assemblies are designed for L10 bearing life exceeding 10,000 hours in typical servo applications.
Q: Do you provide installation support or technical drawings?
A: Yes. Contact support@konmask.com with your application details and we will provide available OEM dimensional drawings, installation guidelines, and torque specifications.
