LP Series (Palletizing Series Robots)

LP Series 130, 190, 210 with text

Advanced palletizing software functions including Path Optimization, Auto Program Creation and Mis-load avoidance increase your productivity.

Nachi Robotic Systems palletizing robots have a Reach up to 3210mm, Payload up to 180/210kg, 4 axis, and Repeatability up to ±0.4mm. The LP Series offers generous horizontal and vertical strokes. A single robot is capable of reaching up to 6 pallets in a single cell. High-speed LP130 can reach 1800 cycles per hour. Air and Control wiring provided to J4 for easy connectivity to your part gripper. Robot floor mounting.

Application Targets

  • Palletizing
  • Material handling
  • Case packing


SRA Series

Nachi SRA models have the fastest 100kg and 250kg payloads in the industry. High-wrist torque and rigid arm provide unmatched motion that can handle the most demanding robotic applications. SRA-H line features a hollow arm structure and best in class spot welding speed and performance.


Versatile, low energy, wide range of applications

Nachi’s latest spot welding technology is integrated into the industry's fastest industrial robots, the Nachi SRA Series, which provides the industry’s most advanced spot welding controls and software functionality. Utilizing fully integrated weld controls, all spot welding data can be directly inputted and monitored through the robot’s teach pendant. A customer is able to create detailed weld schedules unique to your application and material types with ease using the full-color touch screen graphical spot welding user interface. Nachi Robotics’ SRA series reduces spot welding times by 30 percent over previous models through improved motion control, improved arm rigidity, vibration suppression, and acceleration performance.

Nachi Robotics SRA robots also offer A-Trac cable management systems to simplify:

  • Routing of power cables
  • Pneumatic lines
  • Water hoses
  • Signal cables to spot welding guns

MR Series 7-axis

Nachi MR20 with text

Unique 7-Axis design distinguishes the MR series from other robotic products by providing increased freedom of motion and achieving optimum robot posture at all times.  The 7th axis allows the MR series to avoid singularities by providing multiple arm posture solutions for a single working TCP.

The innovative design structure offered by the MR series makes it excellent for machine tending applications allowing the robot to be placed to the side of the machine, providing an open front for machine maintenance.  The MR20 provides an impressive 1260mm of reach at 20Kg payload or up to 30Kg if using a 1000mm envelope.  Floor and Invert mounting solutions are available to maximize work cell flexibility and reduce the automation floor space required.

MR series robots are also capable of working cooperatively to perform complex assembly tasks boasting an impressive ± 0.06mm repeatability.  When combined with a robot slider the MR series can tend many machines using a single robot, drastically reducing automation costs.
