There exist all kinds of linear actuators which manufacturers typically supply to consumers. They embrace:
Ball Screw Actuators: These linear actuators merge a ball-screw and a DC motor gearbox into one unit. The actuator is often full, ready for installation and serve in numerous functions, from agricultural, medical, to industrial.
Worm Drive Actuators: Are actuators fitted acme screw for typical use in lifting chairs, dental and medical gear, and health and mobility products. Consumers can choose them with or without power provide and self-management methods which can be UL approved.
Acme Screw Actuators: Are a mixture of acme screws and DC motor gearbox into one ready-to-set up system. When individuals count on rugged and reliable performance, these linear actuators are favorred. They also serve in air flow, solar tracking, gardens and lawns, ATV, and medical appliances.
VSJ Collection: These linear actuators are more practical and applied in ground cleansing gear, treadmills, practical industrial machines, and gear for house healthcare. They encompass acme screws fitted in either DC or AC versions.
VI Series: These actuators proffer great versatility which makes them effective in operations that relate to lawns and gardens, medical gear and in agricultural and ATV appliances. They exist in either acme or ball screw ranges and will be in DC or AC variations in response to the task to perform.
Small Compact VMD collection: These are greatly compact electric linear actuator actuators. They're utilized in food preparation gadgets, automotive and office functions, and usually in light load tasks.
Apart from classifying linear actuators based on market availability, they can be labeled based on mechanisms of operation. In such classification, there are:
Mechanical Actuators: These can both be mechanical with digital micrometer readout or touring screw in roller screw actuator. Mechanical actuators are used to convert rotary movement to linear motion via either of the next mechanisms:
Screw: The screw shaft follows in line with the rotating nut of the actuator. That is the principle of operation of screw jack, lead-screw and roller screw linear actuators.
Cam: They operate like wedges but with little travel.
Wheel and Axle: Linear actuators working based on this principle include the winch, chain drive, inflexible chain, belt drive, winch, pinion and rack, hoist and inflexible belt.
Liquid underneath Pressure Actuators (Hydraulic Actuators): Pressure is utilized to a piston and conveyed by way of a liquid to a load piston, after which the exterior load is moved. Examples are equipment managed by hydraulic pumps and the hydraulic automobile jack.
Compressed fuel actuators: Are similar in principle to hydraulic actuators, except, uses gas instead of liquid.
