140mm and 168mm Winch Slip Rings for Offshore Applications

Built for Power, Precision, and Harsh Marine Conditions

Penlink’s 140mm and 168mm winch slip rings are advanced electro-optical solutions purpose-built for heavy-duty offshore operations where high voltage, high current, and modular adaptability are mission-critical. These large-format slip rings are designed to thrive in the most demanding marine environments—handling saltwater exposure, intense vibration, mechanical shock, and extreme temperature variations with ease.

With proven performance in ROV launch and recovery systems, LARS & TMS platforms, seismic survey winches, and deck machinery, these slip rings offer unmatched reliability and customization. Whether your application requires up to 5000V, 80A, or 56 signal channels, Penlink’s modular architecture allows for tailored configurations that meet the specific electrical, data, and fiber-optic needs of your system.

These slip rings are fully compatible with:

  • Industrial protocols: Ethernet, Profibus, RS485, COAX
  • Fiber connectors: ST, FC, SC, LC
  • Optical transmission: Single-mode and multi-mode, up to 24 channels
  • Environmental protection: IP66 sealing, with options integrated heaters, and air purge systems

Whether installed topside or subsea, Penlink’s 140mm and 168mm slip rings are trusted by engineers in offshore energy, marine robotics, and oceanographic research for their durability, signal integrity, and long service life.

Application Areas
  • ROV winch systems
  • Offshore cranes and deck machinery
  • Subsea deployment platforms
  • Seismic and oceanographic survey equipment
  • Naval radar stations
  • Rotor/wind sails
  • Shore power systems
Configuration Example
Sizes Voltage/Current No. Channels Sealing Degree Material
Ø140mm 3300V/20A (configurable) 4 IP66 SS304/316
Ø168mm 3300V/80A 12 IP66 SS304/316

Design Advantages

  • Fiber Brush Technology: Enables clean, debris-free signal transmission with up to 8 million revolutions, reducing maintenance and electrical noise.
  • Smart Sectioning: Power, signal, and data rings are optimized for voltage and ampere requirements, ensuring safe and efficient transmission.
  • Fiber-Ready Structure: Ready for integration with FORJ (Fiber Optical Rotary Joint) with up to 24 channels.
  • Modular Build: Customizable lead exits, gland types, and ring configurations to match your system’s needs.
