What is a Rotary Damper?

A rotary damper is a mechanical component that provides smooth, controlled motion by utilizing the viscous resistance of oil. By slowing the movement of an application, it helps prevent sudden operation, reduces noise, absorb impact, and enhances safety, resulting in a more comfortable user experience. Our rotary dampers are easy to install, highly durable, and maintenance-free.

Continuous Rotation Angle Rotary Damper

Rotary dampers are divided into two types: partial rotation angle dampers and continuous rotation dampers. The appropriate type can be selected based on the application’s motion and required opening angle, ensuring optimal performance for a wide range of applications.

Partial rotation angle damper mechanism

Partial rotation angle dampers are designed for applications with a limited rotation angle.

Partial rotation angle damper basic principle

Partial rotation angle damper motion

There are three types of operation: horizontal, vertical, horizontal & vertical. The operation type changes by changing the high-torque position.

Continuous rotation damper mechanism

Continuous rotation dampers have no limited opening angle and exert torque endlessly.

Continuous rotation damper motion

The combination of a continuous rotation damper and rack gears allows linear motion to be buffered at a constant speed.

The wide range of applications for rotary dampers

Rotary dampers are used in a wide variety of applications, including automotive interiors, store fixtures, furniture, and home appliances. For example, they provide smooth, controlled motion for pull-out cup holders and center console lids in vehicles, prevent bakery display shelves from closing too forcefully, and slow the return of movie theater seats. These dampers are ideal for supplication requiring quiet, safe, and controlled opening and closing of hinges and lids. They are also available in a variety of specifications to meet different application requirements, including high-load capacity, heat resistance, or for space-constricted installations. Rotary dampers can help improve product quality, enhance use experience, and increase the overall value of the finished product.

Application mounting examples and installation instructions

Rotary dampers can be selected based on a variety of specifications, including diameter, torque, material, and direction of rotation. TOK’s comprehensive lineup provides solutions for a wide range of applications.
