SPS93 stabilizer actuator kit

SPS93 stabilizer actuator kit
90mm shaft, for VF1650 fins


Silent and reliable construction

The height inside the boat is often the key measurement to allow for installation in modern boats. The SPS66, SPS92 and SPS93 are typically 25% to 75% lower than others. Side-Power actuators for the Vector fins™ are constructed for easy installation and minimal noise reproduction.

SPS66, SPS93 and SPS92 features

Technical design benefits:

  • Precision machining and assembly secures a long lifetime and durability.
  • No additional centre lock, this is automatic in the standard hydraulic system – very safe due to the hydraulics having extreme safety limits – actually stronger than the shaft.
  • Dual cylinders provide
    - balanced load unlike single cylinder solutions.
    - less bearing load, thereby allowing for a more compact shaft bearing assembly.
  • Purpose-designed dual shaft sealing - superior to standard Simmer Ring lip seals.
  • Internal hydraulic connections on actuators are pre-fitted, the installer only fits non-moving hoses/pipes - Easier and safer.
  • No complex adjustments required to set up controller with lots of factors, these are set automatically on first sea-trial of the boat.
  • Bearing the lifetime lubricated SKF high-load bearings transferring the cylinder forces to the fins, have a built-in tightening system. This means that when you on most brands would change all bearings quite often to remove a small noise from a minimal bearing wear, you can instead just tighten them again and keep going. Saving both cost and hassle to get the bearings changed.
  • Fins are installed and removed very easy and quickly from the outside for best convenience in for example transport or other haul-out situations where this might be needed.
  • Defined shaft-shear point in cDefined shaft-shear point in case of the fins accidentally hitting something.
  • All wet parts in stainless steel.
