1. Weight
Measure the moving lid, cover or seat component including attached parts.
Application engineering
Custom rotary damper, positioning and motion-control engineering support from Uniwise.

Selection logic
When a standard damper does not fit, Uniwise can review special torque, positioning behavior, drive interfaces and custom structures. All products support special torque customization.
The final damper or hinge selection should also consider movement speed, friction, springs, installation space, rotation direction and the number of damping elements.
Measure the moving lid, cover or seat component including attached parts.
Measure the pivot-to-CG distance. If the exact center of gravity is unknown during development, share the overall geometry and an approximate pivot position; the engineering review can refine it later.
Define opening angle, desired closing time or free-stop behavior.
Validate the selected or customized torque on the actual mechanism.
