KUKA 00-106-446 – Precision Axis 1-3 Gearbox for KR 150 / KR 180 / ZH 150 / ZH 180 | KUKA KR C Series
Engineering Background
The KUKA 00-106-446 is a factory-original precision gearbox (reducer) engineered for the axis 1–3 drive train of KUKA’s heavy-payload KR 150 and KR 180 series robots, including the ZH 150 and ZH 180 shelf-mounted variants. Designed to KUKA’s exacting tolerances, this unit delivers the torsional rigidity and backlash control demanded by high-cycle automotive, foundry, and heavy-assembly automation lines.

Proven Application Environments
- Automotive Body-in-White: Spot welding and material handling lines requiring sustained 150–180 kg payload capacity at high duty cycles.
- Foundry & Die Casting: ZH shelf-mount configuration for overhead part extraction in thermally aggressive environments.
- Heavy Assembly: Engine block and transmission assembly stations where axis repeatability directly impacts torque-bolt quality.
- Palletizing & Logistics: High-throughput end-of-line palletizing with continuous multi-shift operation.
- Maintenance & Overhaul (MRO): Direct OEM-compatible replacement to minimize robot downtime during scheduled or emergency maintenance.
Engineering Advantages
- OEM Dimensional Compatibility: Exact bolt pattern, shaft interface, and housing geometry — no field modification required.
- Backlash Control: Maintains KUKA-specified angular backlash limits to preserve TCP repeatability (±0.06 mm class).
- Torsional Rigidity: High-stiffness gear train sustains rated torque under shock-load conditions typical of heavy-payload cycles.
- Sealed Lubrication System: Factory-filled with KUKA-approved grease; compatible with standard KUKA re-lubrication intervals.
- Thermal Stability: Rated for continuous operation across industrial ambient temperature ranges without derating.
System Architecture & Signal Flow
In the KR 150 / KR 180 kinematic chain, the 00-106-446 gearbox sits between the axis servo motor output shaft and the robot structural arm link. The servo drive (KSD / KPP) delivers torque commands via the KR C controller; the gearbox reduces motor speed and multiplies torque to drive the arm link through its working envelope. Correct installation torque on the mounting flange and proper grease fill level are critical to achieving rated service life — refer to KUKA documentation BA KR 150/180 for torque specifications.

Technical FAQ
Q: Is 00-106-446 compatible with both KR 150 and KR 180?
A: Yes. The gearbox is a shared component across the KR 150, KR 180, ZH 150, and ZH 180 variants within the same robot generation. Always confirm with your robot serial number.
Q: What is the difference between KR and ZH variants?
A: KR denotes floor-mount configuration; ZH (Zentralhand) denotes shelf/ceiling-mount configuration. The gearbox unit itself is mechanically identical — mounting orientation and cable routing differ.
Q: Can this gearbox be used on KR C4-generation robots?
A: The 00-106-446 is catalogued for the KR C / KR C2 generation. KR C4 variants may use a different part number. Please provide your robot type plate data for confirmation.
Q: Do you supply new or refurbished units?
A: Both options are available subject to stock. Please specify your requirement at inquiry stage. All refurbished units are fully inspected and tested.
Q: What is the typical lead time?
A: In-stock units ship within 2–3 business days. Out-of-stock lead time is 2–4 weeks depending on sourcing. Contact us for real-time availability.
