Slip Ring Manufacturing & Supply

Collector Ring Rebuild, Complete New or Repair

Slip rings are electromechanical interfaces used in the transmission of electrical current from a stationary unit to a rotating assembly. They will operate in one of two ways. One method requires the center core to remain stationary while the brushes and housing rotate around the slip ring. The alternative option occurs when the brushes and housing remain stationary while the center core with the slip ring rotates.

EMCC has extensive experience manufacturing slip ring assemblies for various industrial applications. Our slip rings can be found in vital machinery and rotating equipment worldwide. We can manufacture slip rings completely new, based on OEM specs, repair,  or retrofit an existing assembly.
