Up to 400mm
Simplified sturdy design is achieved via the completely beltless structure.
Utilizing direct connection to the speed reduction gear, tip rotation maintains high accuracy and rigidity even at high speed.
YAMAHA’s award winning SCARA robots are backed with over 30 years of innovation.
With multiple sizes and feature these robots handle a wide variety of processes and applications.
Low Cost High Performance Robot YK400XR
New SCARA robot YK400XR developed by redesigning evenmechanical components of conventional models. This
SCARA robot gives the high quality and high performance,and yet superior cost performance.
YK400XR developed by redesigning even mechanical components of conventional models, are introduced.
Arm length： 400mm
Maximum payload： 3kg
01 Shortest Cycle Time in this class
A standard cycle time of 0.45 sec. is achieved by drawing out the robot performance to its maximum level.
02 Superior Cost Performance
Most economical price in YAMAHA's similar robot class without sacrificing its existing features.
03 With Versatile and High Performance Controller RCX340
Combination of YK400XR robot and new RCX340 controller enable operation up to 16 axes with simple easy networking.
