What are linear hydraulic dampers?

Linear dampers are components used to control motion and ensure smooth and controlled deceleration in a wide range of applications.

Watch our linear dampers overview video to understand how they work and where they are used.
 

Linear hydraulic dampers are the ideal solution when you want smooth deceleration when opening or closing a door, or when raising or lowering an object, such as a car armrest.

Linear hydraulic dampers enable control of the speed of moving parts, preventing shocks and noise and significantly extending the life cycle of the product on which they are installed.

Linear dampers are also referred to as linear speed limiters or deceleration devices in certain applications.

How do linear hydraulic dampers work?

In a linear hydraulic damper, the kinetic energy of the moving object is transferred through the steel rod to the valve inside the damping cylinder. The hydraulic fluid is pushed through the valve, generating friction: when the spring returns the valve to its original position, the hydraulic fluid flows back into the damping chamber.

Linear dampers work in one direction only, as the viscous fluid only exerts resistance in one direction.

For example, it is common for the door of a cupboard to only move more slowly when closing: in this case a linear damper is preferred.

Applications of linear hydraulic dampers

Linear hydraulic dampers are used on many applications such as ovens, refrigerator doors, trash cans, furniture, and electronics.

In the automotive sector, linear hydraulic dampers are used in the center armrest, 2nd and 3rd row seating and other high load applications to facilitate opening and closing.
