Rotational Dampers

Rotational dampers are machine elements that operate like mini-gears to slow down or inhibit the motions of moving pieces of machinery. They enable the controlled opening and closing of flaps, caps, lids and covers in machine equipment.

These dampers slow down circular movement to absorb impact, vibration and noise that may damage the equipment or prevent them from working at their best.

Damped stop gates (similar to latches) on these elements prevent noise and vibration from entering the machines. The high viscosity fluid inside the dampers absorbs the external shock and vibration.

Rotational dampers are more durable than linear dampers because they are sealed permanently.

What are rotational dampers used for?

Rotational dampers are used in industries that manufacture products like cabinets, vehicles, CD players and even toilet seats. Any product or device with a lid, hinge, pull-out drawer or flap can use these components to facilitate a smooth opening and closing motion.

Types of rotational dampers

Rotational dampers can have fixed or variable damping (absorption) rates.

These products are available in plastic or metal materials. Choosing the right type depends on the machinery they are to be used with.
