Not sure which damper? We'll size it with you.
Rotary dampers are specified to the application, not picked off a shelf. Tell us the load and the motion, and an application engineer returns a recommended family, torque code and mounting.

02Motion. Continuous spin, a fixed swing angle, or adjustable — and the speed you want.
03Direction. Right, left or two-sided damping, plus any space or material limits.
