Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the KUKA 00-104-986 RV-410F-236. Always verify mounting dimensions, ratio, and torque ratings before substitution:
- Nabtesco RV-410F-236 — OEM-equivalent cycloidal reducer; direct form-fit replacement
- Nabtesco RV-320F-236 — Lower torque class; suitable for lighter-duty axis substitution
- Nabtesco RV-500F-236 — Higher torque class; uprated alternative for demanding cycles
- Sumitomo Cyclo BBB Series (equivalent ratio) — Cross-brand cycloidal option; requires adapter verification
- KUKA 00-104-987 / 00-104-985 — Adjacent KUKA part numbers; confirm ratio and flange compatibility

Selection Guide
Use the following criteria to confirm the correct gearbox for your application:
- Step 1 — Verify Part Number: Cross-reference KUKA 00-104-986 against your robot BOM or spare parts list.
- Step 2 — Confirm Reduction Ratio: RV-410F-236 — the suffix denotes the gear ratio. Do not substitute a different ratio without reconfiguring the robot controller.
- Step 3 — Check Torque Class: RV-410F indicates ~4,100 N·m rated torque. Ensure application load does not exceed this.
- Step 4 — Flange & Mounting: Confirm output flange bolt pattern and input shaft dimensions match your robot arm housing.
- Step 5 — Condition Preference: Choose new OEM, certified refurbished, or exchange unit based on budget and lead-time requirements.

Replacement & Compatibility FAQ
Q: Can I use a Nabtesco RV-410F-236 to replace KUKA 00-104-986?
A: Yes. The KUKA 00-104-986 is based on the Nabtesco RV-410F-236 platform. In most cases it is a direct replacement, but always verify the output flange configuration for your specific robot model.
Q: Is the gear ratio 236 critical?
A: Yes. The robot controller motion parameters are calibrated to the exact ratio. Substituting a different ratio will cause positioning errors and may damage the robot.
Q: Do you offer exchange / core return programs?
A: Yes. Contact us with your failed unit details for an exchange pricing quote.
Q: What is the typical service life?
A: Under normal operating conditions and proper lubrication intervals, RV-F series gearboxes typically achieve 10,000–20,000 operating hours.
Q: Can Konmask provide a certificate of conformance?
A: Yes, upon request for new OEM units. Refurbished units include an inspection report.
