6.3.1. Fulcrum Bearings
Vibration, abnormal sound and overloads are observed when a fulcrum bearing is
damaged. When the Nut holding bearings becomes loose, bearing play occurs. It
may damage the bearings.
Diagnostics
① Shake the 1
st
ARM and 2
nd
ARM back and forth to check if bearing
exhibits any play. (In case of using a chain block, check the bearings for
the play, with the 1
st
ARM and 2
nd
ARM posture maintaining and without
any overload to the reduction gear.
② Check to see if the robot touched other peripheral equipment before the
malfunction.
Resolution
① Replace the bearing. A Chain Block is needed to lift and hang the robot
ARM. Contact our service office for any difficulties..
