Rotary Dampers
FRT-E2-300

Small and lightweight for finest braking

Continuous Rotation
Damping torque 0.026 +/- 0.007 in-lbs

The damping direction of the smallest ACE FRT-E2 rotary dampers with plastic body is rotating on both sides. They can brake directly in the pivot point or linear through a gear and gear rack. 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 0.026 +/- 0.007 in-lbs

Damping direction bidirectional

Gear without

Construction size Ø 0.39 in

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 32 °F to 122 °F

Pressure angle 20°

Material Outer body, Shaft, Gear: Plastic

Mounting In any position

Tooth Involute gearing

P.C.D. 0.24 in

No. of teeth 10

Module 0.6

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.

On request

Special designs available on request. Toothed plastic racks (modules 0.5 to 1.0) are available for the rotary dampers with pinions.
