Design & Construction
Fabricast Self-Contained 1.00 inch bore slip rings are engineered as enclosed rotary units intended to support larger internal pass-throughs while keeping installation straightforward. The conductive system uses coin silver rings paired with silver graphite contact elements to support steady electrical transfer during continuous rotation.
All electrical components are housed within a rigid enclosure that establishes fixed brush positioning and electrical spacing. This integrated construction removes the need for separate alignment of rotor and brush assemblies and provides a controlled internal environment suited for longer duty cycles and higher mechanical loads associated with the larger bore size.
Configuration Flexibility
Standard electrical layouts can be adjusted to accommodate different voltage levels, current ratings, and signal groupings while maintaining the benefits of a fully enclosed assembly.
Fabricast works with customers to customize lead styles, wire lengths, and exit locations to match system packaging and routing needs, allowing the slip ring to integrate cleanly into automation, inspection, and defense platforms without unnecessary complexity or additional mounting hardware.
Typical Applications
Self-Contained 1.00 in Bore Slip Rings are commonly used in rotary systems that require additional internal clearance while benefiting from a fully enclosed, pre-assembled design, including:
- Industrial automation equipment
- Rotating inspection and vision systems
- Robotic platforms with integrated shafts or cabling
- Test stands and measurement equipment
- Defense and surveillance systems with moderate pass-through requirements
