The flat disc brake for two-sided damping

Continuous Rotation
Damping torque 77 +/- 7.08 in-lbs

The damping direction of the flat constructive ACE rotary damper FDT with robust steel body is two-sided rotation. It can brake directly in the pivot point of the square receptacle. ACE rotary dampers are maintenance-free and ready-to-install.

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

Technical Data

Damping torque 77 +/- 7.08 in-lbs

Damping direction bidirectional

Construction size Ø 1.85 in-lbs to 2.76 in-lbs

Rotational speed max. 50 rpm

Lifetime 50,000 cycles (1 cycle = 360° left-hand, 360° right-hand). 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 14 °F to 140 °F

Material Outer body: Steel; Output shaft sleeve: Nylon

Mounting In any position

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.
