Core Design Features
-
74mm Large Through-Bore Structure
The 74mm central through-hole allows for easy integration of shafts, hydraulic lines, or fiber optic cables, enabling flexible system design for complex rotating equipment. The hollow shaft design simplifies installation and reduces overall system footprint. -
Integrated Inspection Window
The built-in observation window enables real-time visual inspection of internal brush and contact ring wear without disassembling the slip ring, drastically reducing maintenance time and downtime. This design is critical for predictive maintenance in continuous-operation industrial systems. -
High-Current & High-Reliability Contact System
- 3 dedicated 200A high-current channels for three-phase power transmission, with parallel-stranded AWG12 wires to minimize resistance and heat generation.
- Precious metal alloy brush contacts ensure low contact resistance, minimal electrical noise, and a service life of over 10 million revolutions.
- Teflon (PTFE) insulation provides excellent high-temperature resistance, chemical corrosion resistance, and dielectric strength, suitable for harsh industrial environments.
-
Premium Material & Craftsmanship
- Tin-plated copper conductors for superior conductivity and anti-oxidation performance.
- Color-coded wires for error-free installation and maintenance.
- Military-grade manufacturing standards, with full traceability for defense and aerospace applications.
Application Scenarios
- Industrial automation & heavy machinery (rotating tables, cranes, lifting equipment)
- Wind power generation (wind turbine pitch systems)
- Aerospace & defense (radar systems, satellite ground stations, military turrets)
- Medical equipment (large CT scanners, rotating medical devices)
- Packaging & printing machinery, and other high-load rotating systems
