The Grizzly planetary speed reducer meets the challenges of the most demanding applications: heavy duty reliability, adaptability to specific customer requirements, and a proven track record with over 30 years of experience.
      The Grizzly is built using accurate, case hardened sun and planet gears placed between large, anti-friction bearings. The sun gear floats, ensuring load sharing equality.
