FEATURED PRODUCTS
Pantograph Heavy Rail (WBL)
Our lightweight, compact pantographs with air bellows drive and optional insulation are ideal for long-distance traffic. They operate quietly, durably, and efficiently, even in extreme conditions. Schunk offers complete, optimized systems with high-quality components, adaptable for freight and high-speed trains, with global support and customization available.
Carbon Collector Shoe for Third-Rail
Our durable carbon collector shoes withstand continuous load and climate stress, offering excellent electrical conductivity and long-lasting performance. Designed for aluminum power rails with stainless-steel surfaces, they provide high thermal resistance and stable performance up to the wear limit. Custom solutions ensure high corrosion resistance and optimal emergency running properties, even enabling speed records.
Cast Collector Shoe for Third-Rail Current Collector
Our durable collector shoes withstand continuous load and climate stress, providing excellent electrical conductivity and long-lasting performance. Made of cast iron or milled steel, they offer high thermal resistance, stable performance, and corrosion resistance. Custom solutions ensure optimal emergency running properties for steel power rails.
Short-circuiter for 3rd Rail Applications
Our short-circuiter for 3rd rail systems ensures immediate de-energization in case of a malfunction, protecting vehicle technology and passengers. The pneumatically actuated switch reliably triggers a short circuit, de-energizing all relevant systems, including the third rail. This high-current resistant design is available as an optional accessory for 3rd rail current collectors.
Axial Grounding System (Externally Mounted)
Our Polyax grounding contacts prevent damage from continuous return currents by safely diverting them via clear paths. Designed for externally mounted bogies, they offer long service life and high reliability. Available in all-carbon variants for de-energized operation and systems for high current densities. Carbon brushes are also available as spare parts.
Axial Grounding System (Internally Mounted)
Our Polyax grounding contacts protect critical components from return current damage by diverting currents through defined paths. Designed for internally mounted bogies, they offer long service life and maximum reliability. Available in all-carbon variants for de-energized operation or high-current systems. Carbon brushes are also available separately as spare parts.
Pantograph Light Rail (SBE, SBF, SBL)
Our pantographs for local transport offer reliable, low-maintenance operation with maximum safety. They feature individually sprung collector strips for consistent contact with overhead lines. Available in three concepts—SBE with spindle drive, SBF with pneumatic lowering drive, and SBL with air bellows drive—they can be customized to meet your needs. Schunk provides complete, high-quality systems and global support.
Gear/Gearbox-mounted CFG Systems
Our patented Carbon Fiber Grounding (CFG) systems protect AC motors from damaging shaft currents, preventing bearing and gearbox damage, noise, heat, and costly shutdowns. Tailored to any transmission or engine, they ensure reliable interference current dissipation, extend vehicle service life, and are easy to install. Resistant to vibrations and customizable for optimal performance.
Pantograph Metro (SBE, SBL)
Our robust Metro pantographs ensure reliable operation for metros and streetcars, available as SBE with spring-electric drive or SBL with air bellows drive. They provide permanent contact with overhead lines via individually sprung collector strips. Compact design suits confined tunnels. Customizations are available. Schunk offers top-quality complete systems and comprehensive support.
Motor-mounted CFG Systems
Our patented Carbon Fiber Grounding (CFG) systems protect AC motors from shaft currents, preventing bearing and gearbox damage, noise, and costly shutdowns. Easily mounted on any engine plate, they ensure reliable current dissipation, extend vehicle service life, and are vibration-resistant. Compact and customizable, they offer easy assembly and disassembly.
Brush Holders for Railway Applications
Our high-quality brush holders ensure precise positioning of carbon brushes in traction motors, offering durability and reliability. We provide a wide range of standard holders and customized solutions, perfectly matched to your rail applications with tailored carbon materials. Matching carbon brushes are also available for an optimally coordinated system.
3rd Rail Collector Shoe
Our 3rd rail current collectors ensure safe power transmission for metros, subways, and monorails, even under tough conditions. They transmit 1000A at 700V, with protection against sparks and optional insulation shields. Available in 40 designs, including spring and pneumatic systems, they offer versatile mounting options. Safety features include fuse boxes, debris protection, and optional shoe catchers.
3rd Rail Current Collector with Fuse Box
Our weatherproof, standardized fuse boxes protect sensitive vehicle technology in metros, subways, and monorails from electrical faults. Made from approved railroad materials, they safeguard fuses from mechanical stress and allow easy replacement without disconnecting cables. They accommodate various fuse sizes, with optional indicator switches for blown fuses. Customizable cable routing is also available.
Customer-specific CFG Systems
Our patented Carbon Fiber Grounding (CFG) systems protect against vagrant shaft currents in AC motors, preventing noise, heat, and costly damage. They ensure reliable dissipation of interference currents, increasing vehicle fleet service life. Resistant to vibrations, easy to install, and customizable, our systems offer fast, tailored solutions to prevent unplanned downtime.
Radial Grounding System
Our Polyrad grounding contacts prevent damage from continuous return currents by reliably diverting them via clear paths. Mounted on the gearbox, they offer long service life and high reliability. Available in all-carbon variants for currentless operation or high-current systems, with customizable solutions. Carbon brushes are also available separately as spare parts.
Carbon Brush for Grounding Contacts
Our carbon-carbon grounding contacts revolutionize signal current transmission, extending maintenance intervals and ensuring long service life.
