The flat damper for constant component protection

Partial Rotation Angle
Damping torque 88.51 in-lbs

The self-compensating FYN-S1 rotary damper with zinc die-cast body provides a constant sequence of movement for different masses. The damping direction can be either right or left rotation. During each reverse movement of the unilateral decelerating versions there is a certain return damping torque that depends on the size. ACE rotary dampers are maintenance-free and ready-to-install.

Rotary damper products are built to metric specfiications. For precise measurements, please refer to the ACE rotary damper catalog or contact an application expert.

Technical Data

Damping torque 88.51 in-lbs

Damping direction left

Construction size Ø 2.36 in

Lifetime 50,000 cycles, even after this time, the dampers still produce over approx. 80% of their original damping moment. The service life may be significantly higher or lower, depending on the application.

Operating temperature range 23 °F to 122 °F

Material Outer body: Zinc die-cast ; Output shaft sleeve: Plastic

Mounting In any position

Rotation angle max. 130°


Damping direction: Right hand damping = damping action in clockwise direction (when looking onto the output shaft or output shaft sleeve, depending on the damper type). A play of approx. 5° can occur at the beginning of movement.

Mounting information

No axial or radial forces may be induced via the shaft.

Safety information

Do not use rotary dampers as supports. Provide an external guide or support.
