SLIP RING INSTALLATION / STATIONARY & ROTATING CONNECTIONS
SLIP RING BASICS
What Is a Slip Ring?
A slip ring transfers electrical power, signals and data between stationary and rotating parts, allowing continuous rotation without twisting cables.
Continuous Rotation
The rotor turns with the equipment while the stator remains fixed. Sliding contacts maintain the electrical connection during rotation.
Power, Signals & Data
Supply rotating motors and sensors with power, and transmit control signals or data. The circuit design must match the electrical ratings and signal requirements.
Select by Your Specifications
Check circuit count, current, voltage, signal type, speed, mounting space and operating environment before choosing a model.

Questions & Answers
Answers to common questions about electrical transfer, mounting and custom selection.
View More Technical Questions →What is the difference between a slip ring and a rotary union?
A slip ring transfers electrical power, signals or data through a rotating interface. A rotary union transfers air or liquid. An integrated assembly can combine both functions.
Can a slip ring transmit Ethernet?
Yes, when the electrical contact system is designed for the required Ethernet connection. Specify the data rate, number of channels, cable and connectors; these requirements cannot be inferred from the circuit count alone.
How do I select a through bore slip ring?
Confirm the required bore diameter, available outer diameter and length, mounting method, speed, circuits and environment. The bore dimension alone does not determine whether a model is suitable.
Can power, data and compressed air be combined?
Yes. Electrical slip rings and pneumatic rotary unions can be integrated in one assembly. Provide electrical ratings, data interfaces, air passage count, pressure, flow rate and port size.
What should I send for a custom slip ring quote?
Send your application, circuit list, current and voltage, signal and data requirements, dimensions, speed, environment, quantity and desired delivery date. Include drawings or photos if available.
Can I request a quote before every specification is confirmed?
Yes. Share what you know and identify the details still to be confirmed. Final product selection, price and delivery schedule depend on the agreed configuration.
