Nachi-Fujikoshi Corporation is one of Japan's oldest and most respected industrial robot manufacturers, founded in 1928. While less prominent than FANUC, Yaskawa, or Kawasaki in global markets, Nachi is a dominant supplier to the Japanese automotive industry and is widely used for CNC machine tending, deburring, welding, and heavy-payload handling. In 2026, Nachi robot prices range from $28,000 for the compact MZ04 to $90,000+ for the heavy SA133 series.
This guide covers Nachi's MZ, SRA, and SA product lines, their 2026 price ranges, and how they compare to FANUC, Yaskawa, and Chinese robot brands.
Quick Answer: Nachi robots cost $28,000–$90,000. The MZ25 (25 kg, 1,667 mm reach) runs $38,000–$55,000. Chinese 6-axis robots with similar payload cost $18,000–$30,000 — a 40–50% saving.
Nachi Robot Price by Series (2026)
MZ Series — High-Speed Compact Arms
The MZ (Multi-purpose, Zero-maintenance) series is Nachi's flagship mid-range lineup, known for among the fastest speeds in its class.
| Model | Payload | Reach | Speed (Vmax) | Repeatability | Price (FOB) |
|---|---|---|---|---|---|
| MZ04 | 4 kg | 541 mm | 10,000 mm/s | ±0.02 mm | $28,000–$38,000 |
| MZ07 | 7 kg | 717 mm | 10,000 mm/s | ±0.02 mm | $30,000–$42,000 |
| MZ12 | 12 kg | 1,441 mm | 9,000 mm/s | ±0.03 mm | $34,000–$48,000 |
| MZ25 | 25 kg | 1,667 mm | 8,000 mm/s | ±0.05 mm | $38,000–$55,000 |
Key MZ advantage: The MZ series achieves 10,000 mm/s maximum TCP speed — among the fastest in the sub-25 kg class. Hollow wrist design allows cable and hose routing through the arm. Can be mounted in any orientation (floor, ceiling, wall, angled).
Applications: CNC machine loading/unloading, pick-and-place, assembly, deburring and polishing, vision-guided inspection.
SRA Series — Heavy Payload Automotive
The SRA series handles 100–166 kg payloads for automotive press tending, spot welding, and body frame handling.
| Model | Payload | Reach | Repeatability | Price (FOB) |
|---|---|---|---|---|
| SRA100B | 100 kg | 2,651 mm | ±0.1 mm | $52,000–$68,000 |
| SRA133 | 133 kg | 2,651 mm | ±0.1 mm | $58,000–$75,000 |
| SRA166 | 166 kg | 2,651 mm | ±0.1 mm | $62,000–$80,000 |
Applications: Automotive body welding, press tending, heavy material handling, die casting extraction, large forging handling.
SA Series — Extra Heavy Payload
The SA series covers 220–700 kg payloads for steel, foundry, and very heavy automotive applications.
| Model | Payload | Reach | Price (FOB) |
|---|---|---|---|
| SA220 | 220 kg | 2,700 mm | $72,000–$90,000 |
| SA400 | 400 kg | 3,100 mm | $80,000–$100,000 |
SX / SC Series — Spot Welding Specialists
Nachi's SX and SC series are purpose-built for automotive spot welding with integrated servo gun control.
| Model | Payload | Application | Price (FOB) |
|---|---|---|---|
| SX Series | 165–200 kg | Body spot welding | $65,000–$85,000 |
| SC Series | 50–165 kg | General spot welding | $50,000–$70,000 |
Nachi vs. Competitors: Price Comparison
| Specification | Nachi Price | FANUC | Yaskawa | Chinese (Estun) |
|---|---|---|---|---|
| 7 kg, 6-axis compact | $30K–$42K | $32K–$48K | $30K–$45K | $14K–$22K |
| 25 kg, 6-axis | $38K–$55K | $42K–$62K | $40K–$58K | $18K–$30K |
| 100 kg heavy | $52K–$68K | $58K–$78K | $55K–$75K | $30K–$45K |
Nachi vs. FANUC: Similar quality tier, slightly lower price on comparable models. Nachi's MZ series speed advantage is meaningful for high-cycle CNC tending. FANUC has a larger global service network.
Nachi vs. Chinese brands: Chinese 6-axis robots cost 40–50% less than Nachi but have shorter MTBF (40,000 vs. 60,000+ hours) and thinner service networks outside Asia.
When to choose Nachi:
- Japanese automotive supply chain requiring Nachi-approved suppliers
- High-cycle CNC tending (MZ series speed is class-leading)
- Automotive body shops needing SRA/SX spot welding solutions
- Users valuing Nachi's 60,000+ hour MTBF reliability
When to choose Chinese alternatives:
- Standard handling and pick-and-place without automotive brand requirements
- Cost-sensitive projects where 45% savings dramatically change ROI
- Applications in markets where Nachi service is limited (US, Europe outside Germany)
Nachi Controller: FD11 / FD Series
Nachi uses the FD11 controller for most MZ/SRA models:
- Supports EtherNet/IP, PROFINET, CC-Link, DeviceNet
- Integrated vision interface for Nachi's optional 2D/3D vision
- Teaching pendant with color touchscreen
- Offline simulation via NachiSim software

Frequently Asked Questions
How much does a Nachi robot cost?
Nachi robots range from $28,000 for the compact MZ04 to $100,000+ for the heavy SA400 series. The most common mid-range MZ25 (25 kg, 1,667 mm) costs $38,000–$55,000. Chinese 6-axis alternatives with similar payload cost $18,000–$30,000.
What is the Nachi MZ series known for?
The MZ series is known for industry-leading speed (10,000 mm/s TCP) and the ability to route cables and hoses through the hollow wrist and arm. This makes it particularly suited for CNC machine tending, where fast cycle times and clean cable management reduce downtime.
Is Nachi a good robot brand?
Yes — Nachi has been making robots since 1969 and supplies major Japanese automakers including Toyota, Honda, and Suzuki. MTBF exceeds 60,000 hours. The main limitation is a smaller global service network compared to FANUC or Yaskawa.
How does Nachi compare to FANUC?
Both are high-quality Japanese brands at similar price points. Nachi's MZ series has a slight speed advantage for compact arms. FANUC has a larger global service network (260+ locations vs. Nachi's more Japan-concentrated support). For non-automotive applications outside Japan, FANUC's broader service coverage often makes it the safer choice.
Where can I buy Nachi robots?
Nachi robots are available through Nachi Robotics' North American subsidiary (nachirobotics.com), European distributors, and Asian regional dealers. Used Nachi robots are available from industrial robot dealers, typically at 35–55% below new price.
