Packaging machinery uses rotary interfaces in indexing, filling, sealing, labeling and inspection systems where power, sensors, encoders and data must cross moving interfaces. Use a slip ring when the machine cycle and washdown or contamination exposure make cable management a reliability risk.
Terminology: packaging-machine slip ring is an application description, not a single product class; define cycle rate, motion profile, signal mix, ingress exposure and service interval.
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
Packaging configurations can include encoder, sensor, actuator, Ethernet and power circuits with connectors or cable exits matched to the machine. Confirm cycle rate, indexing profile, washdown or contamination exposure and maintenance interval.
Choose the interface after documenting motion profile, circuit function and environment. Compare through-bore when center routing or a larger mixed-service package simplifies the machine.
Compare through-bore, capsule and hybrid architectures against the machine envelope, circuit schedule and service requirements.

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.
