Design & Construction
Fabricast Self-Contained 2.00 inch bore slip rings are configured for large rotating assemblies where internal routing and mechanical layout dictate the overall system design. The electrical interface uses coin silver conductors working with silver graphite contact elements to support stable power and signal transfer during continuous rotation.
All functional components are enclosed within a rigid housing that establishes fixed internal alignment and electrical separation at the factory. This structure supports predictable performance in assemblies with higher rotational inertia and larger pass-through requirements.
Configuration & Application Support
Self-Contained 2.00 in Bore Slip Rings are offered in a range of circuit counts and electrical layouts to accommodate custom power and signal requirements. Beyond standard configurations, Fabricast routinely adapts internal ring spacing, brush arrangements, and conductor sizing to support higher voltages, increased current capacity, or mixed signal types within the same assembly.
Lead styles, exit orientations, and termination options can be tailored to suit specific routing constraints and enclosure designs. This flexibility allows the slip ring to be configured as a purpose-fit component within large rotating systems rather than a fixed, off-the-shelf assembly.
Typical Applications
Self-Contained 2.00 in Bore Slip Rings are typically selected for large-format rotating systems that require maximum internal clearance within an enclosed electrical assembly, including:
- Radar and antenna platforms
- Large sensor arrays and rotating enclosures
- Defense and aerospace subsystems with bundled cabling
- Industrial turntables and rotary platforms
- Custom machinery with oversized shafts or internal routing needs
