2. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   A traveling-nut linear actuator has a motor that stays attached to one end of the lead screw (perhaps indirectly through a gear box), the motor spins the lead screw, and the lead nut is restrained from spinning so it travels up and down the lead screw. A traveling-screw linear actuator has a lead screw that passes entirely through the motor.

3. Segmented spindle - Wikipedia

   en.wikipedia.org/wiki/Segmented_spindle

   A segmented spindle, also known by the trademark Kataka, is a specialized mechanical linear actuator conceived by the Danish mechanical engineer Jens Joerren Soerensen during the mid-1990s. [1] The actuator forms a telescoping tubular column, or spindle, from linked segments resembling curved parallelograms. The telescoping linear actuator has ...

[ 1 ] is an American manufacturer of mechanical power transmission products – brakes , clutches, couplings, and the like.

5. Moving magnet actuator - Wikipedia

   en.wikipedia.org/wiki/Moving_magnet_actuator

   A moving magnet actuator is a type of electromagnetic linear actuator. [1] It typically consists of an arrangement of a mobile permanent magnet and fixed coil, arranged so that currents in the coil generate a pair of equal and opposite forces between the coil and magnet.

6. Rigid belt actuator - Wikipedia

   en.wikipedia.org/wiki/Rigid_belt_actuator

   A rigid belt actuator, also known as a push-pull belt actuator or zipper belt actuator, is a specialized mechanical linear actuator used in push-pull and lift applications. The actuator is a belt and pinion device that forms a telescoping beam or column member to transmit traction and thrust. Rigid belt actuators can move dynamic loads up to ...

7. Valve actuator - Wikipedia

   en.wikipedia.org/wiki/Valve_actuator

   Gate Valve with Handwheel (L) and with Linear Pneumatic Actuator (R) A linear actuator opens and closes valves that can be operated via linear force, the type sometimes called a "rising stem" valve. These types of valves include globe valves, rising stem ball valves, control valves and gate valves. [2] The two main types of linear actuators are ...
