Used Nachi Robots for Sale 6

Nachi-Fujikoshi Corporation leverages its broader industrial component expertise — bearings, cutting tools, hydraulic equipment, and special steel — in manufacturing industrial robots that benefit from the company's deep understanding of precision mechanical components and their operating requirements.

The SRA series provides heavy-payload capability specifically designed for automotive spot welding — the original and still dominant Nachi robot application. SRA robots handle the combination of high payload, fast axis speeds, and sustained duty cycles that spot welding on automotive body-in-white production lines demands. The mechanical design reflects decades of refinement for this specific application.

The MZ series compact high-speed robots deliver among the fastest cycle times in their payload class for assembly, machine tending, and pick-and-place applications. The compact arm design fits into confined cell layouts where larger robots from competing manufacturers cannot physically operate. MZ robots from 3 kg through 25 kg payload suit electronics assembly, small parts handling, and compact machine tending applications.

The MC series provides mid-range handling capability between the compact MZ and heavy SRA platforms, addressing general material handling, palletising, and machine loading applications in the 20-70 kg payload range.

The FD controller series provides the current platform with modern programming, connectivity, and safety features. Earlier controller generations remain functional but with progressively limited software capability and connectivity options.

Nachi's pricing is typically competitive with larger Japanese robot competitors — Fanuc, Yaskawa, and Kawasaki — reflecting the company's smaller robot market share while matching or exceeding competitor capability in specific application areas, particularly spot welding and compact high-speed handling.

Service and spare parts support through Nachi's global distribution network covers major Asian and European automotive manufacturing markets. Service coverage outside these primary markets should be verified for specific regions.

Browse used Nachi robots on Exapro to compare SRA heavy-payload, MZ compact high-speed, and MC mid-range handling models from verified sellers worldwide.

When evaluating used Nachi robots on Exapro, check axis repeatability and speed performance, verify FD controller generation and installed software options, inspect cable harness condition throughout the arm including the dress-out for welding applications, test all safety circuits and emergency stops, and confirm that the robot's specifications match your application requirements.
