• Failing bearings affect the palletizing accuracy, and in severe cases, the
workpiece may fall down uncontrolledly.
• The gripper part or workpiece may fall down.
• Vibration would result in the reduction of the life cycle of the pneumatic
cylinder and affect the palletizing accuracy.
• Worn bearings
• Loose bolts
• Worn steel sleeve in the trunnion assemly or lack of lubrication between the
steel sleeve and the trunnion.
• The buffer mechanism of pneumatic cylinders are unproperly adjusted.
Action
Determine which bearing is emitting the noise.
Make sure the bearing has sufficient lubrication.
Replace the bearing to a new one.
Action
Determine which bearing is emitting the noise.
Tighten the bolts to the recommended torque.
Action
Periodically inject lubrication between the steel
sleeve and the trunnion.
If worn serisouly, replace the trunnion assembly.
