Rotary damper mechanism

A rotary damper is a small tool that can be incorporated into many devices, enabling them to operate with a smooth and controlled motion. 


The working mechanism is very simple and it is based on the torque, i. e. the intensity of resistance.

The torque of a rotary damper


A rotary damper is filled with a viscous fluid, such as a silicone oil or grease, and its torque is determined by the viscosity of the fluid and the shape of the rotor rotating inside the device.


Continuous and non-continuous dampers


There are two types of rotary dampers: continuous and non-continuous. Both of them operate by rotation about a single axis, rotary dampers can provide resistance in clockwise (one-way), anti-clockwise (one-way) or both (two-ways) directions.

Continuous dampers can freely rotate beyond 360°, while non-continuous dampers cannot rotate beyond 360°.
