Rotary Dampers

Efdyn offers an extensive line of Kinetrol rotary dampers and rotary dashpots. Our units are precision fluid dampening devices that give a smooth resistance to shaft rotation, which increases with angular velocity.
These viscous dampers are available for either limited rotation or continuous rotation applications. As with all of Efdyn’s products; these are the most rugged and dependable units on the market.
Rotary dampers and rotary dashpots are used for speed control, shock absorption, slipping drives, mechanical delays and much more.
