Nonmagnetic retaining ring is a critical component of heavy turbonator, one of the components bearing the highest stress, and by means of the retaining ring the centrifugal force is borne on the location of turning of the coil block on the both ends of the rotor.

The retaining ring is hot assembled on the both ends of the rotors to compact the coils on the ends to prevent the coils of rotors during high speed operation from runaway damages which might cause disastrous accidents to the power stations.


We can manufacture all kinds of the retaining ring and can also manufacture according to the custmer's specific requirements.
Our advanced technical process for forging and cold expanding guarantees the high product quality.
