A slip ring consists of two parts, the one is stator part, the other is rotor part. The stator part often fixes the contact and the rotor part often put the ring. The relative rotation of two parts can ensure alignment by two horizontal bearings.
Two working styles of slip rings

1）Cylinder working type of slip ring

The ring and the ring is arranged along the axial direction. For this slip ring type, more rings with longer axial length, but each ring spinning speed is the same, which can well guarantee the working life of slip rings. Structure chart is as follows.

2）Disc working type of slip ring

The ring and the ring is arranged along the radial direction. For this slip ring type, more rings with bigger OD(outer diameter), but with small overall height, which can be well applied to those devices that have limitations on height or length. Structure chart is as follows
