Introduction:
The linear actuator is equipped with a waterproof breather valve, which allows air to freely flow in and out of the cylinder. When the linear actuator is running, a pressure difference will be generated inside and outside the cylinder, and air will flow in and out of the cylinder through the breather valve to ensure that the pressure inside and outside the cylinder is balanced. At the same time, the breather valve will prevent impurities such as water and dust from entering the cylinder. In this way, the internal components of the linear actuator are effectively protected, ensuring that the linear actuator can operate for a long time in damp conditions without experiencing performance degradation or damage.
Application:
It has a wide range of applications, mainly for scenes with high requirements for noise level and waterproof level. Such as water entertainment, on-water or on-board equipment, aquaculture, sewage treatment systems, outdoor electric windows and doors, irrigation devices and other water-related industrial automation equipment, household equipment and medical equipment.
And it is mainly used for doors, windows, cellars, trapdoors, hatchways, solar tracking system, medical devices, agricultural machinery, vehicles, ships, elevator platforms, lifting tables, TV lifts, robots, cabinets, massage sofas, electric beds, medical chairs, and other electrical equipment. It can open, close, push, pull, lift, and descend these devices.
It can replace hydraulic and pneumatic products to save power consumption.

Operation:
When the brown power wire is connected to the positive pole of the DC power supply and the blue power wire is connected to the negative pole of the DC power supply, the stroke rod will extend outward; after switching the power in the reverse direction, the stroke rod will retract inward.

Stroke and Length (Model 0041937)
| Parameter | Value |
|---|---|
| Stroke | 250 mm |
| Retraction Length | 380 mm (center distance between two mounting holes when the linear actuator is fully retracted) |
| Extension Length | 630 mm (center distance between two mounting holes when the linear actuator is fully extended) |
The linear actuator has two built-in limit switches, When the linear actuator is fully retracted or fully extended, it will stop automatically.
We can adjust the position of the built-in limit switches during production to meet customer-specified stroke and retraction lengths.
Note 1: The specified stroke must be less than the standard stroke of the ordered actuator. For example, a specified stroke of 230 mm is less than the standard stroke of the ordered actuator (250 mm). In this case, the retraction length will be reduced by an equivalent value, resulting in a retraction length of 360 mm. Of course, you can also choose to retain the original standard retraction length of 380 mm.
Note 2: The specified retraction length must be less than the standard retraction length of the ordered actuator. For example, a specified retraction length of 355 mm is less than the standard retraction length of the ordered actuator (380 mm). In this case, the stroke must also be reduced by an equivalent value, resulting in an effective stroke of 225 mm.
Different Speeds and Corresponding Maximum Thrust
| No-load Speed | Full load Speed | Maximum Thrust | Self-locking Force |
|---|---|---|---|
| 5±1mm/s | 3±0.5mm/s | 3500 N / 350 kg / 780 lbs | 3500 N / 350 kg / 780 lbs |
| 6.5±1mm/s | 3.5±0.5mm/s | 3000 N / 300 kg / 670 lbs | 3000 N / 300 kg / 670 lbs |
| 10±2mm/s | 5.5±1mm/s | 2500 N / 250 kg / 560 lbs | 2500 N / 250 kg / 560 lbs |
| 13±2mm/s | 7±1.5mm/s | 2000 N / 200 kg / 450 lbs | 2000 N / 200 kg / 450 lbs |
| 16±3mm/s | 8.5±2mm/s | 1500 N / 150 kg / 340 lbs | 1500 N / 150 kg / 340 lbs |
Note:
1. The above data is the maximum load capacity that can be obtained when the linear actuator runs in the vertical direction. If the weight of your equipment (such as a cellar door) is 100kg, and you want to use a linear actuator to open this door, you need to calculate the actual force acting on the linear actuator according to your installation method. This force is usually 2-5 times the weight of the cellar door. If you don't know how to calculate it, please contact us for help.
2. The above is the speed at no load, and the actual working speed will gradually slow down as the load increases. Full load speed is approximately 60-70% of No-load speed.
3. Different speeds correspond to different maximum loads. Please select the right speed according to the speed and maximum load you need.
4. Linear actuators are not recommended for continuous operation under maximum load, we recommend letting it work at about half of the maximum load to get a longer working life.
5. For linear actuators with a stroke greater than 500MM, you should not normally allow them to operate at their maximum stroke under heavy loads. If the actual stroke you want is 600MM, we recommend that you choose a linear actuator with a stroke of 700-800MM.
6. The maximum pull force of the linear actuator is slightly less than its maximum thrust force.
Production Time & Return or Exchange Policy
The linear actuators are customized and not in stock, and we need to spend 3~7 working days to produce them according to the specified parameters in your order, so that we don't accept returns or cancel orders. If customers order unsuitable linear actuators themselves, we also do not accept exchanges, please understand.
