3. How to replace a ball screw of the PU-axis (Single, Double)
The design of the PU-axis for YG series machines varies depends on the model and the size of the
board.
The PU-axis motors of the YG100R (KHV) and YG88R(KHW) are equipped with intermidiate shaft.
The PU-axis motors of YG100(KGS), YG88(KGR) and YGD(KGM) are direct-drive, and the conveyor
width and the layout of the single and double PU-axis vary as shown in the figure below.

3.1. How to remove the ball screw of the PU-axis
* This section describes how to replace the PU-Axis ball screw taking a single PU-axis of YG88 and
YG100 models as an example.
1. Please make sure to perform Return-to-origin and turn off the machine before replacment.
Caution:
The driving motor of the PU-axis (AC servo) is equipped with a brake, and the brake is applied except
when the motor is rotating. Please do not rotate the shaft with the brake applied.
2. Remove the bolts on the upper surface of the push-up that fix the plate 1 with a hex wrench in
order to remove the plate 1.
Caution:
As the plate 1 is heavy, please be careful not to damage the conveyor frame by banging the plate on it
or drop it.
