Wrist Speed Reducer and Bearing

Check if the three wrist axis move smoothly or not. If the wrist does not move smoothly, contact your
Yaskawa representative. Removing and disassembling the wrist to find the faulty axis will be needed for
repair or replacement of the bearing, the speed reducer, or the sealing compounds.
To remove the wrist from the U-arm, firmly hold the wrist and remove the fixing bolt. If not, the wrist
may fall down when the fixing bolt is removed.
