A manual linear actuator is a device that changes the motion of a machine part into linear motion or a straight line.
Screw actuator
The screw actuator works by changing circular motion into linear motion. The design looks like a large metal screw. When the screw is turned, it moves an object along the straight line. This type of actuator is very popular and used in many places like car seats, lifting systems, and door controls. One good thing of this actuator is that it is very strong. It can lift or pull heavy things. Also, it does not need any power source and works well in places with high electricity needs or in bad weather. However, it may be slow to move and can wear out faster from regular use than other actuators.
Rack and pinion actuator
This actuator uses gear teeth to change circular motion into linear motion. The gear teeth are called the pinion. The rack is a flat bar with teeth that looks like a straight line. When the pinion turns, it moves the rack back and forth. This actuator is quite strong and offers a good speed. It is not as heavy as screw actuators. So, the rack and pinion actuator is often used in places like moving parts of a machine, cars for steering, and camera systems. It gives decent speed and can handle average loads easily. However, the main drawback is that it cannot lift or bear as much weight as the screw actuator. Also, the gears may need lubrication regularly so they keep working smoothly.
Belt actuator
The belt actuator uses a belt to move things back and forth. The actuator pulls or pushes objects by contracting or expanding like a muscle. Compared to the screw and rack actuators, this type is lighter and very good for moving lighter things over longer distances. For that reason many people use it in 3D printers, sliding doors, and conveyor belts. Yet, the strong pull and push force is not there. It may not work well if heavy items are always pushing or pulling on it. The actuator may wear out faster from regularly moving heavy objects back and forth through short distances.
Below are some key specifications and details about their maintenance requirements for manual linear actuators.
Guides:
Appropriately selected guides are critical for the normal operation of linear manual actuators. They ensure stable movement and dispersion of loads. Users can select guides according to the load capacity, friction coefficient, and supporting methods. Regular cleaning and maintenance of guides is also very important. This can prevent dust and dirt pollution, keeping the guides' precision and smoothness.
Travel limit:
Limit switches can set the traveling range of manual linear motion actuators. Users can adjust their positions according to the application's needs. They should regularly check and ensure that the limit switches are in the correct position. Therefore, it ensures that the actuator will not exceed its preset traveling range and avoid possible damage.
Push force:
It represents the maximum load that a manual linear actuator can support. Although it is not directly related to maintenance, users should choose the appropriate thrust according to the task. They also need to consider factors such as weight and working frequency during use. If the push force exceeds the specified value, it may lead to the actuator's early failure or damage.
Speed:
Speed refers to the moving speed of manual linear motion actuators. Users can choose the proper speed according to the application's needs. They should also establish a reasonable working frequency. Otherwise, it may cause overuse and early wear. When using the actuator, users can also inspect the speed to ensure that it is within the normal range. If there is any abnormal change, they should find out the reasons and deal with them promptly.
IP ratings:
IP ratings are protection levels against dust and water. Users should select appropriate IP-rated linear actuators according to the working environment. If the working environment is relatively harsh, they may also need to take additional protective measures to ensure the actuator's reliability and stability in operation.
In summary, guides, limit switches, thrust, speed, and protection level are essential components of manual linear motion actuators. Users should pay attention to selection and adjustment when using them. Moreover, regularly inspect and maintain these parts for the actuator's normal operation and long-term stability. Manual linear actuators are still delicate despite being simple. Therefore, they should be cared for to ensure they remain usable for a long time. Neglecting small tasks can lead to significant expenses down the line. Users should establish a maintenance routine so that any minor issues can be fixed before deteriorating into something more severe.
Manual linear actuators are widely used in all kinds of scenarios from industrial to household to assist in controlling movement in a variety of machines.
Vehicle Repair
When the car is immobilized due to a minor part needing replacement, a manual linear actuator can come in handy in providing the needed car part with the help of a simple push or pull. It can also be used when replacing a car part instead of using a machinery or equipment that works on electricity.
Solar Energy
The panel can be manually adjusted in varying angles when the sun passes the horizon, hence manually maximizing solar energy with the help of the actuator.
Medical
In the medical field, a large number of linear manual actuators are utilized in hospitals, nursing homes, and home care facilities. Medical equipment must be adjustable to accommodate patients of various heights and weights. As a result, beds, stretchers, and other equipment must be mobile. The equipment cab be adjusted with ease at the time of admission, discharge, and transfer medical procedures, which is done by sliding the patient in a bed or stretcher that can be easily moved with the help of the actuator.
Sailboats and Yachts
Manual actuators are extensively employed to control blockades and sail tension in addition to gangway. The manual linear actuator is great for because it is economical and simple to use. When not under the influence of gravity, tension must be maintained, and this is done by the actuator, steering the vessel with great ease and comfort.
Stage and Studio Sets
Manual actuators can be used in varied occasions like theatre plays and drama, fashion shows and even in the film industry can be utilized. The moving props can be moved smoothly and easily by now moving parts of the play or stage with ease and comfort. It eliminates the need of manpower, and it can be moved and set at the very right point and time with great ease and comfort.
Steps and Ramps
When the escalator and elevator are not in function and the stairs need to be constructed or set up in a particular way, a manual actuator can come in handy which can be used to build stairs in an easy and simple way without the need of electrical power. It can also be used in ramps for the handicapped and old individuals in a very smooth and easy manner.
Entertainment
In all areas of amusement sectors from theme parks to entertainment parks to children parks to safari parks to water parks to zoological gardens to aquariums and safari parks to water parks to museums to theatres and drama to film industry to advertising industry and many more to innumerable ways where a grey or black heavy duty linear manual actuator is used one way or the other. An actuator can be used to create centre pieces, special effects, costume changes and many more in a play that needs to be done smoothly and easily with a push or pull rather than going to a specific technical area and need and requirement.

Q1: What are the benefits of using a manual actuator?
A1: Manual actuators are simple to set up and use. They don't require any extra energy source and are cheap to fix and run. In case of a power outage, they can still work, providing reliable control and acting safely in emergencies.
Q2: What are the three basic types of actuators?
A2: The three basic types of actuators are electric actuators, hydraulic actuators, and pneumatic actuators. Manual linear actuators also fall under the category of mechanical actuators since they use physical force to move.
Q3: How does an actuator work?
A3: An actuator is a device that converts energy into motion. It usually consists of a motor and gearbox assembly and may include elements such as encoders and brakes. An actuator receives a control signal from a controller that indicates the desired position or state. The controller may be programmed to respond to particular conditions or inputs. The actuator then converts the electrical energy into mechanical energy, turning a shaft that can then move or turn something.
