Our history goes back to 1959

It all began with the Sisu radial piston hub motor, invented by the company Sisu Auto Oy. Designed as part of the wheel hub, this motor gave the timber trucks required extra pull force to survive the extreme road conditions.

The Black Bruin hydraulic motor is a newer version of the original Sisu motor, with exactly the same working principle by radial pistons pushed against the cam ring. Today’s Black Bruin motor saw the light of day in the early 1980’s and the development to meet the ever increasing industry demands continues.

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.
