What is it?
The Nachi MZ25 is a 6-axis industrial robot with 25 kg payload, 1,685 mm reach, and ±0.03 mm repeatability. The highest-payload model in the MZ-series, the MZ25 addresses heavy machine tending, packaging, and material handling tasks at the boundary between mid-range and heavy industrial robots. Its extended 1,685 mm reach covers large machining centre footprints and wide assembly cells.
Who is it for?
- Japanese automotive tier suppliers handling medium-heavy castings, engine components, and transmission parts
- Packaging operations running palletising assist and case handling at 15–25 kg payload across extended reach
- Machine tenders servicing large CNC turning centres and horizontal machining centres from a single base position
- Electronics manufacturers handling server chassis, large power supplies, and rack-mounted assemblies
Key specs

How it compares
The Fanuc M-20iB/25 (25 kg, 1,853 mm) has 168 mm more reach at the same payload. The Universal Robots UR20 (20 kg, 1,750 mm) is collaborative at 5 kg less payload. For guarded high-speed cells at 25 kg across 1,685 mm in Japanese supply chains, the MZ25 provides Nachi service and parts continuity; the Fanuc M-20iB/25 is preferred for maximum reach.
Limitations
- Not collaborative; full safety guarding required
- Fanuc M-20iB/25 provides 168 mm more reach at the same payload class
- Nachi's global integrator network is smaller than Fanuc's and KUKA's
- FD controller expertise concentrated in Japan and East Asia
FAQ
What is the Nachi MZ25 payload and reach?
The MZ25 has a 25 kg payload and 1,685 mm reach, the highest payload in the MZ-series. It covers heavy machine tending and packaging across large working envelopes.
What repeatability does the MZ25 achieve?
The MZ25 achieves ±0.03 mm repeatability, consistent with the MZ12. This is appropriate for machine tending, material handling, and packaging at 25 kg payload.
What applications is the MZ25 best suited to?
The MZ25 is best for heavy machine tending, automotive parts handling, packaging, and material transfer in guarded cells. It is standard in Japanese automotive and electronics manufacturing at the 20–25 kg payload range.
How does the MZ25 compare to the Fanuc M-20iB/25?
The Fanuc M-20iB/25 has the same 25 kg payload at 1,853 mm reach — 168 mm more than the MZ25. For applications where reach is the constraint, the Fanuc is preferred; for Nachi-incumbent plants requiring service continuity, the MZ25 is the natural choice.
How does the MZ25 compare to the Universal Robots UR20?
The UR20 is collaborative with 20 kg payload at 1,750 mm reach — 5 kg less payload but 65 mm more reach. The MZ25 requires guarding but operates at higher speed. For high-throughput guarded cells, the MZ25 is faster; for flexible collaborative deployment, the UR20 is preferred.
