Design & Construction
Fabricast self-contained 0.50 inch bore slip rings are built as fully integrated rotary assemblies, combining the conductive elements, brush system, and housing into a compact, enclosed unit. Coin silver rings and silver graphite contacts are used to support stable electrical transfer, while the enclosed architecture helps protect internal components from contamination and handling damage.
The self-contained housing maintains fixed brush alignment and electrical spacing without requiring separate mounting of brush blocks or rotors. This configuration simplifies installation and supports consistent rotational behavior in applications where space, weight, and assembly time are tightly controlled.
Configuration & OEM Adaptability
Self-Contained 0.50 in Bore Slip Rings are available in multiple circuit counts and electrical configurations. Fabricast supports application-specific adaptations, including lead styles and electrical layouts, to help OEMs integrate the slip ring cleanly into compact rotary systems.
Typical Applications
Self-Contained 0.50 in Bore Slip Rings are commonly selected for compact rotary systems where ease of integration and space efficiency are priorities, including:
- Small automation assemblies
- Compact robotics and rotary actuators
- Instrumentation and test fixtures
- Medical and laboratory equipment
- Lightweight defense and surveillance devices
- Rotating sensors and inspection systems
