Technical Specifications

Solving the Discontinued Hardware Crisis

The Yaskawa HP20 and HP20D were workhorses of automotive, metal fabrication, and general assembly lines throughout the 2000s and 2010s. Many facilities running these robots have no immediate budget or operational window for a full cell replacement. The L-axis speed reducer is a high-wear component — it absorbs the mechanical load of the lower arm through thousands of duty cycles per day. When it degrades, symptoms appear gradually: increased positioning error, abnormal joint noise, and eventually a hard fault that takes the robot offline.

Condition & Reliability Assurance

Every unit shipped by DriveKNMS passes a structured 5-step inspection protocol before dispatch:

• Step 1 – Visual and Mechanical Inspection: Housing integrity check, seal condition, input/output shaft runout measurement.
• Step 2 – Electrolytic Capacitor Assessment: Where integrated drive electronics are present, capacitor aging and ESR values are evaluated. Aged capacitors are flagged and disclosed.
• Step 3 – Firmware and Label Verification: Part number, revision code, and manufacturing date codes are cross-checked against Yaskawa documentation to confirm authenticity and compatibility.
• Step 4 – Pin and Connector Corrosion Inspection: All mating surfaces, connector pins, and ground points are inspected under magnification. Oxidation is treated or the unit is quarantined.
• Step 5 – Functional Rotation Test: The gearbox is rotated under load simulation to confirm smooth operation, absence of binding, and acceptable backlash within OEM tolerance bands.

Condition grade (New / Refurbished-Grade-A / Tested-Used) is disclosed in full on every invoice. No unit is shipped without a passed inspection record.

Key Features for System Maintenance

• Drop-in replacement: Identical mounting pattern, shaft dimensions, and gear ratio to the original OEM assembly. No mechanical modification required.
• No reprogramming required: The robot controller (XRC, NX100, or equivalent) does not require parameter changes when replacing a like-for-like speed reducer. Calibration is limited to standard zero-point mastering.
• Avoids engineering reconstruction costs: Replacing this gearbox preserves the existing robot program, tooling offsets, and cell layout. A new robot platform would require full path reprogramming, safety validation, and production requalification — typically 4–8 weeks of engineering time.
• Extends asset life by 5–10 years: A functioning L-axis drive restores the robot to full rated payload and repeatability. For facilities with stable production requirements, this is a direct alternative to capital expenditure.
• Supports legacy controller compatibility: Verified compatible with Yaskawa XRC and NX100 controller generations commonly paired with the HP20/HP20D platform.

Q: How do I confirm this is a genuine OEM part, not a counterfeit?
A: We provide full photographic documentation of the part number label, serial number, and inspection records prior to shipment. Customers may request a video inspection call before purchase. We do not source from unverified secondary markets.

Q: Can this part be used with the HP20D variant?
A: The HP20D shares the same L-axis drive assembly as the HP20. Confirm your robot's serial number and axis configuration with our technical team before ordering if there is any uncertainty.
