Troubleshooting

Phenomenon Refer phenomenon below for failure occurs to the rotary joint

Cause Countermeasures

Rotation failure (Galling)

Not rotate Not rotate smoothly Noise is made during rotation

1) Galling of the sliding part due to the impact when operation source starts or stops

Replace the rotary joint, To provide flexibility and to absorb shocks, Install rubber or resin coupling which has better performance in absorbing center misalignment, shocks and vibrations. Adjust center misalignment between the drive and fixed axes within allowable center misalignment of the coupling. (See P.7,10 Precautions)

2) Galling of sliding part due to lateral load.

Replace the rotary joint. Keep the lateral load within allowable radial load. (P.2 Specification)

3) Galling of sliding part due to the rotation impact of power transmission.

Replace the rotary joint. This rotary joint can not be used as a bearing for transmitting power from a drive source such as a motor. (P.7 Precaution)

Air leakage Air leakage to naighoring port more than allowable lekage(P3).

1) Galling of sliding part Increased rotation resistance. This leads to wear out fixed O ring due to sleeve rotating.

Replace the rotary joint. Refer Rotation failure above.

2) Galling of sliding part increased rotation resistance. This applies excess load to gasket, and gasket is displaced.

Replace the rotary joint. Refer Rotation failure above.

Breakage Parallell pin of adapter plate is damaged

2) Failure due to excess load and the rotation impact of power transmission.

Replace the rotary joint. This rotary joint can not be used as a bearing for transmitting power from a drive source such as a motor. (P.7 Precaution)

2) Failure due to excess load caused by galling of sliding part.

Replace the rotary joint. Refer Rotation failure above.
