Key Applications

The SP013018-MR series is ideally suited for marine & offshore equipment:

  • Real-time strain gauge and thermocouple signal acquisition
  • Continuous rotation data and power transmission
  • High-speed precision measurement systems

Technical Advantages

  1. Gold-Gold Contact Technology
    • 99.99% pure gold plating for ultra-long service life
    • 200% longer lifespan than silver-graphite contacts
  2. Precision Concentricity
    • Integrated casting ensures ≤0.01mm concentricity between ring grooves and bearings
  3. Mirror Surface Finish
    • Contact surface roughness reaches Ra0.02 (optical mirror quality)
    • Reduces friction loss by 40%
  4. Ultra-Precision Machining
    • Dimensional tolerances <0.01mm (ISO 2768 H grade)
    • 5-axis CNC processed for thermal stability
  5. Near-Zero Pressure Brush Design
    • Extends service life by 33% through reduced mechanical wear
    • Self-lubricating PTFE composite brushes
  6. Rugged 304 Stainless Steel Housing
    • Excellent sealing resists dust, moisture, and corrosion
    • Suitable for harsh industrial environments

Physical Dimensions

  • Diameter: 25.4mm
  • Lead Wires: 400mm standard (custom lengths available)
  • Mounting Holes: 4-M2.5 threaded holes (16±0.1mm pitch)

Factory Validation

  • 100% burn-in tested at 120% rated speed
  • Certified by ISO 9001:2015 quality system
  • Dynamic resistance monitored for 72 hours post-production

Engineering Excellence

Our manufacturing facility combines precision machining, rigorous testing, and ISO-certified quality control to deliver slip rings that exceed industry standards for marine & offshore equipment.
  • Advanced friction pair technology for specific application requirements
  • Proprietary mirror processing technology for contact surfaces
