What is a Slip Ring?

Slip Rings are a type of electro-mechanical device which can transmit power, electrical signals or data between a component which is stationary or fixed and a component which is rotating. Depending on the application, slip rings have different features to ensure they are well suited for the job in hand.

Slip Rings are used within applications where there is unrestrained, intermittent or continuous rotation and power or data needs to be transmitted. Slip rings are used to improve the mechanical performance of a system or to simplify the operation. They are also used as a way of eliminating the messy and interfering wires which may be present when using other types of components which require rotation.

Slip rings are sometimes referred to as rotary electrical joints, collector rings or electrical swivels. They are often chosen for use with AC motors where they are used to transfer resistance to the rotor windings.  

What is a Slip Ring Used For?

Slip rings are often used throughout many industries – some of the industries we have encountered for slip rings are:

  • Oil & Gas
  • Agriculture
  • Water Treatment
  • Construction
  • Medical
  • Electronics
  • Aerospace

To function within these industries correctly, products must be designed and manufactured to certain standards. The slip rings that we offer have different features based on where they are intended for use.

Slip rings are used in any application where an electrical contact needs to be maintained during the rotational motion between the two contacts. Applications include:

  • Rotating turrets
  • Electric motors
  • Bottle labelling machines
  • Rotary tables
  • Wind turbines
  • Machine tools
  • Printing machines
  • Control systems
  • Video systems
  • CCTV systems
  • Rotary Tables

Benefits of using a Slip Ring

As stated above, slip rings are often chosen for applications as a way of keeping wires from moving parts to a minimum. Other benefits include:

  • Cost-effective
  • High quality
  • Long life
  • IP protection rated
  • Well suited to extreme environments

Many of our slip rings have their own benefits depending on the application and the environment, for this reason we invite you to contact us with your requirements for us to find the right product for you.
