An integrated slip ring rotary union combines electrical transmission with pneumatic or hydraulic media transfer in one engineered rotating assembly. Use it when packaging, alignment, routing and service requirements are best solved as a coordinated interface rather than as separate components.
Terminology: integrated rotary union may combine slip ring, rotary union, FORJ or RF functions. Specify every service path and the mechanical interface together.
Specifications to verify
The table below is a configuration checklist, not a blanket performance claim. Confirm the selected values against the approved drawing, test method and quotation for the exact assembly.
Configuration values are confirmed against the approved drawing, test method and quotation for the selected assembly.
Available configurations and selection guide
Integrated assemblies can combine electrical circuits with pneumatic, hydraulic, fiber or RF services. Available configurations depend on service routing, isolation, sealing, bore, ports, mounting, speed and the interaction between each path.
Choose an integrated architecture when coordinated packaging and alignment matter more than separate commodity interfaces. Define every service path before comparing alternatives.
Compare through-bore, capsule and hybrid architectures against the machine envelope, circuit schedule and service requirements.

Approved dimensional drawing
Attach the approved drawing revision or link to a Slip Ring USA datasheet; do not substitute an unverified range image.
Applications and case-study evidence
Integrated assemblies are evaluated when a machine combines power, control, data, fluid, fiber or RF services through the same rotating center and packaging or alignment must be coordinated.
Datasheet status: request a Slip Ring USA-branded PDF with the RFQ so the document matches the exact configuration and drawing revision.
Engineering questions
What is a through-bore slip ring?
It is a rotary electrical interface with a hollow center that allows a shaft, cable bundle or other service to pass through while power, signals or data cross the rotating interface.
When should I choose through-bore instead of capsule?
Choose through-bore when the machine needs center routing, a larger envelope, or more complex mixed-service integration. Choose capsule when the assembly is compact and no center opening is required.
Can a through-bore slip ring carry power and data together?
Yes, when the circuit mix, shielding, impedance, contact system and test method are engineered for the required protocols and data rates.
What details determine service life?
Speed, direction changes, duty cycle, current, contact material, vibration, contamination, temperature and sealing all affect life. The target should be tied to a stated test condition and expected revolutions or years.
Can the center pass pneumatic, hydraulic or fiber services?
The bore can provide routing space, but a combined assembly must be checked for bend radius, sealing, pressure, flow, fiber alignment, mounting and rotational constraints. Use the family-specific RFQ fields to define those requirements.
