Slip ring

What is slip ring?

Slip ring is very important component and parts that can solve the 360 degrees continuous rotating , and get electricity to a continuously rotating part of my assembly, rotate without limits. Slip rings are used in electromechanical device including motors, AC generator. DC generator.Common slip rings are through bore slip ring. pancake slip ring. pneumatic slip ring, wireless slip ring, wire slip ring.


Moflon slip rings (electrical joints) reliably transfer data and power from stationary sources to rotating parts

Our slip ring products are used across a wide range of industries including factory automation, heavy equipment, machine tool, packaging, medical, oil and gas, defense, and aerospace.

We offer standard electrical slip ring product lines that feature high-performance brush technology and are grouped by design type and circuit configurations.

If our inventory of standard slip ring products isn’t a fit for your project, we can provide a custom-tailored slip ring solution designed to meet the exact circuits, ratings, and design parameters required for your application.

Slip Rings FAQs

  • How do I choose a slip ring ?

    Proper selection of a slip ring solution requires details about your application's operating parameters including total circuits, voltage and amps per circuit, operating speed, and mounting type. A good place to start your search is with our Standard Slip Rings. If you are confident that a custom / modified solution is most likely required or need assistance in your selection, contact us . Our experts are here for you.
  • What aspects effect the life of a slip ring assembly ?

    The life span of a slip ring is dependent upon the contact materials employed, the operating environment, the rotational speed, vibration etc.
  • Why do we use slip rings in motors ?

    A wound rotor induction motor has a stator like the squirrel cage induction motor, but a rotor with insulated windings brought out via slip rings and brushes. however, no power is applied to the slip rings. their sole purpose is to allow resistance to be placed in series with the rotor windings while starting.
  • What is so special about Moflon slip ring transmitters ?

    Moflon slip rings employ contact materials and methods which have been tried and tested over many years. This core contact technology is used exclusively in combination with highest quality materials for the rotor and stator. Only optimally matched cables and plugs are chosen for the connections.
  • What electrical circuits can pass through a slip ring ?

    Electrical circuits commonly requested to pass through a slip ring are, power, bus signals, encoder signals, etc..
  • Do you offer custom slip rings ?

    Yes, we work directly with our slip ring partners to design custom solutions to meet your exact electrical requirements. For more information please see Custom Slip Rings.
