SKF Rotostat sealing module with sensor
The intelligent combination of dynamic and static seals bonded directly to a metal carrier or retainer with an integrated engine management sensor and trigger wheels.

  • Simple, ready-to-install one piece modular unit
  • Choice of elastomeric, PTFE or low friction dynamic sealing lips
  • Moulded in place static seal and centering dowel pin
  • Pre-assembled complete module with the sensor and high resolution magnetic trigger wheel
  • Optional integration of magnetic trigger wheel and sensor to provide input to the engine management system

  • Combines multiple components into one unit, saving installation time and costs while avoiding installation errors
  • Reduced inventory due to reduced number of components
  • 50% reduction in leak paths
  • T-joint static gasket feature improves static sealing
  • Weight reduction of up to 30% compared to assembled die cast retainer
  • Total system development and responsibility at SKF to ensure compatibility between sensor and trigger wheel

For the optional sensor system:
  • Signal to provide crankshaft position and rotational speed
  • Magnetic trigger wheel with high accuracy and reduced angular errors for precise signal to engine management systems
  • Sensor outside crankcase, thus no cable sealing problems and easy replacement
  • Improved system accuracy by performing timing at the flywheel location (high mass flywheel and best rotational “smoothness”)
