Pitch Control Units

Our pitch control units are shaft line units designed to be installed aft of a standard reduction gearbox without built in pitch control.

This system has many advantages:

  • In combination with a conversion from fixed into a controllable propulsion system.
  • If a very noise and vibration free installation is required.
  • If a reverse function in combination with a CPP system is required.

The shaft line pitch control units all have built in thrust bearing, long stroke for feathering propeller, and can be delivered with semi-flexible foundations.

We made our first pitch control units in 1929 for the Hundested engine in connection with our propeller system. We have used this extensive experience to update our units through the years.

Our pitch control units are ideal solutions in the mega yacht industry. We have also delivered units to fishing vessels and ferries.

Pitch Control Unit


We can supply three different types of pitch control units. The difference is in the way the pitch is activated: It can either be electrically (FR-ELC) or hydraulically (FR-HP) activated. We can also supply a system (FR-HFC) with an O.D. box built on to an existing reduction gearbox without built in pitch control.
