Install these rotary speed limiters at the hinges of small lids, doors, and access panels for smooth, quiet motion. They're often used in electronics applications.

Speed limiters with a 105°, 110°, or 130° rotation angle are commonly used for small movements, such as closing lids.

Speed limiters with a 360° rotation angle are often used to move small hoods, flaps, and fans. A cycle is one shaft rotation.

Dual direction speed limiters dampen motion in both directions. Common uses for them include controlling the motion of a switch-activated door and opening and closing a DVD player.

Clockwise and counterclockwise speed limiters dampen motion in the listed direction, moving freely in the opposite direction. Use them in processes that require returning a part to its original position.

Speed limiters with a geared shaft must be used with gears that have the same 20° pressure angle and module.

Speed limiters with adjustable torque have a knob on the back to control damping torque. Use them in applications that require fine tuning.
