Vertical multi-joint robots, also known as vertical articulated robots, have joints similar to human shoulders, elbows, and wrists, allowing them to perform complex movements similar to human arms. Most vertical multi-joint robots have six degrees of freedom, and theoretically, with six axes, they can cover the position and posture of the end effector in a comprehensive manner. The more axes there are, the more diverse positions can be achieved, increasing the versatility of the robot.

• Places where bearings are fastened with low axial force.
• Places where forward/reverse motion is repeated.

• In places where smooth movement is required, we were able to fasten in places where fastening with low axial force is required.
• The maintenance cycle has been greatly extended, and the operating time has been extended, improving productivity.
