A rotary damper is a rotational device to decelerate an objective’s movement, either rotary or linear movment.
The key difference between them lies in their force curve. In limited-angle dampers, the torque varies at different angles, whereas in infinite-angle dampers, the torque remains consistent across all angles.
They feature two vanes attached to the rotation shaft, acting as a valve. As the rotary damper operates, the shaft drives the vanes, creating resistance in one direction only. When the shaft rotates, the silicon oil flows gradually through a one-way valve, generating rotational torque. Due to their internal structure, limited-angle dampers have a maximum working angle of 110°.
On the other hand, infinite-angle dampers, such as gear or disk dampers with a one-way clutch, allow continuous rotation in one direction while providing resistance. This is achieved by engaging the clutch to control motion in the desired direction and disengaging it for smooth movement in the opposite direction. This design is essential for applications requiring controlled motion over an unlimited range of rotation in one direction.

Material used of the damper:
Zinc alloy and steel are commonly used in high torque dampers, but for low torque dampers, plastic (PBT, PA, or POM) can also fulfill the task. Adding glass fiber to plastics also increases the strength of the material.
