Constant Torque Spring with a Rotary Damper

Quick answer: A damper primarily influences motion speed; it does not replace the static torque balance. Select the spring and damper for different requirements.

Does a damper correct a torque mismatch?

At rest, the load still needs an appropriate balancing or holding system. During motion, damper resistance may vary with speed and temperature. An acceptable slow sweep does not prove controlled release at maximum speed. Record the motion conditions used to choose both parts.
