Rotary Damper Barrel Damper For keyboard

Keyboard dampers are rotary dampers that mount at the hinge-point and are designed to fit into computer conference table. A typical application is keyboard. The design of middle through hole is easy to install. The damping direction of the rotary dampers with continuous rotation can be uni-directional, bi-directional. In rotary dampers with continuous rotation, a fluid damping is produced by the shearing or braking force of silicon fluids resistance between the surfaces of a rotor and a stator. The damping moment is determined by the viscosity of the fluid and the size of the orifice or gap. The damping characteristics can be customized by changing the viscosity of the silicon fluid or by changing the structure of the rotor and stator. Our keyboard barrel dampers can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
