Selection Guide
Use the following criteria to select the correct U-axis reducer for your YASKAWA robot:
- Step 1 – Identify robot model: Check the robot nameplate for model and serial number.
- Step 2 – Confirm axis: U-axis = 5th axis (wrist bend) on most Motoman 6-axis robots.
- Step 3 – Match part number: Use HW9381442-DEPX2900L for standard U-axis; use HW0380024-FEPX2900U for high-load variants.
- Step 4 – Verify gear ratio: Standard ratio is 1:100 (confirm with robot maintenance manual).
- Step 5 – Contact us: Send your robot model + controller type for free part confirmation before ordering.

Replacement & Compatibility FAQ
Q: Can HW0380024-FEPX2900U directly replace HW9381442-DEPX2900L?
A: In most Motoman robot models, yes — both share the same mounting flange and gear ratio. Confirm with your maintenance manual or contact us.
Q: Is SRDA-SDB95A01A-EDX100MPL800 a drop-in replacement?
A: SRDA-SDB95A01A is a servo drive unit; EDX100MPL800 refers to the motor/reducer assembly. They are part of the same drive train but are not identical to the standalone reducer. Contact us for clarification.
Q: Do you supply refurbished units?
A: Yes. Refurbished units are fully tested and come with a 90-day warranty. New OEM units are also available.
Q: What is the lead time?
A: In-stock items ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time.
