Harvester rotators

The Black Bruin radial piston rotator is the professional’s choice for productive harvesting. The rotator’s excellent performance is based on a durable piston-cam ring technology. The torque excels in even the most demanding situations and the rotator maintains a firm grip throughout machines service life. Thanks to the innovative structure, the torque-transmitting components are wear-proof, releasing no harmful particles into the hydraulic system.

Long service life with torque that lasts

The Black Bruin rotator is extremely accurate in use and responds precisely and consistently to user’s control. Drivers are known to highly appreciate the many advantages of the piston technology because control of the harvester head or grapple is natural and superior in all situations. And in contracting work that translates into high productivity and eco-friendliness!

Key features and benefits

  • Low operating costs, easy to service if needed – Service life can be extended far into the future
  • Wear-proof torque-transmitting components – No harmful particles into the hydraulic system
  • Extremely accurate in use – Responds precisely and consistently to user’s control

For the love of the craft: ”How to get your job done more easily and all in one go”

Jussi Antman is a superpower. Because he never intends to stop learning. This man who has run his own company specialising in regeneration and thinning felling for a proud 20 years has a profound understanding of the harvester rotators of different makes and brands – their links and brakes. And at the end of the day the end result is clear: ”I like this one best – the harvester and the rotator.”

The feeling of pure strength

Logger Pierre Ragnarsson knows why so many forest machine drivers prefer radial piston rotators over vane rotators: “Apart from the superior durability and smooth maintenance, what I like most about the Black Bruin rotator, is the feeling of pure strength. The brake is insanely stable, nothing that shakes the unit during acceleration – it is a very smooth ride, much more comfortable for us who drive the machines. I just love it.”

Black Bruin hydraulic rotators – Long service life with torque that lasts

“With Black Bruin’s radial piston motor design, rotator remains powerful throughout its service life, generally 8000 to 13,000 hours, whereas rotators powered by vane motors tend to get looser over time,” says Aki Laaja, Managing Director of Metsä-Multia.
