Our story goes back to 1959

Logging in Finland began to shift from horses and floating to timber trucks in the 1950s. The combination of heavy loads and poor roads led to the need for increased pulling power. Responding to this demand, Finnish engineer Ilmari Louhio (1919-2015) developed the hydraulic SISU radial piston motor, which was designed as part of the wheel hub.

Black Bruin’s modern hydraulic motors operate according to the same basic principle as the original design from 1959: Pressure pushes the pistons and cam rolls outwards against the cam ring on the housing. The waveform of the cam ring transforms the force into torque.

Since the 50’s many strong companies in Finnish metal industry have contributed to the development of the Black Bruin motors: SISU, Partek, Valmet, Metso and Sampo Rosenlew.
