How to Choose a Linear Actuator by Force: 900N to 7000N

Choosing a linear actuator by force alone can lead to the wrong product. A better starting point is to identify the force range, movement direction, stroke requirement, voltage, protection level, duty cycle, and mounting geometry of the application.

HyHaven's electric linear actuator range covers several force levels so that customers can start with the application and then move to the appropriate model. This guide is intended to explain the range at a high level. Always confirm the exact variant, stroke, price, and availability on the individual product page before ordering.

Start with the required force range

Force is usually expressed in newtons (N) or pounds-force (lbs). The required actuator force depends on more than the static weight of the mechanism. Friction, leverage, wind, acceleration, mounting angle, and side loading can all change the real requirement.

Use the force range as an engineering screening step, then check the complete mechanism. Do not select a model only because its headline force is larger than the load shown on a scale.

How to choose between the models

When a lower-force model may be appropriate

U1 and U2 can be starting points for mechanisms where the calculated force requirement is lower and the installation benefits from a smaller force class. The correct choice still depends on the mounting geometry and the actual movement resistance.

When to consider a higher-force model

U11, U3, and U6 belong in a higher-force comparison when the mechanism has a larger load, more resistance, or a more demanding linkage. Higher rated force does not automatically make a model suitable: the structure, brackets, power supply, controller, duty cycle, and safety supports must also be designed for the application.

Force is not the only specification

• Stroke: confirm the required travel and the fully retracted and extended mounting dimensions.
• Voltage: match the actuator version to the control system and power source.
• Speed: confirm whether the mechanism needs slow positioning or faster movement.
• Duty cycle: check how often and how long the actuator will operate.
• Environment: treat IP54 and IP65 as product protection ratings, not as a substitute for application-specific weather protection.
• Geometry: avoid side loading and confirm the line of action through the full travel.

Questions to answer before ordering

1. What is the required push and pull force at the actuator mounting point?
2. What stroke and installation length are required?
3. Is the load static, dynamic, or affected by wind and acceleration?
4. Will the actuator operate intermittently or repeatedly?
5. Which voltage version matches the controller?
6. What protection is required at the motor, cable connections, and surrounding mechanism?

Final selection principle

The right actuator is the model that matches the complete application, not simply the model with the largest number. Compare the force class first, then confirm stroke, voltage, speed, duty cycle, mounting geometry, protection, and availability on the product page.

Quick answers before you compare models

Is a higher force rating always better?

No. Oversizing can create unnecessary structural, electrical, and safety requirements. Calculate the force at the actuator mounting point, including leverage, friction, acceleration, wind, and a practical safety margin.

How do I choose between 900N and 7000N?

Use force to narrow the range, then confirm stroke, installation length, voltage, speed under load, duty cycle, IP protection, and mounting geometry. A model is not a confirmed fit until the complete mechanism is checked.

Can I use IP54 or IP65 outdoors?

These are product protection ratings, not a guarantee that a complete installation is waterproof, saltwater-proof, or weather-certified. Protect cable connections, controls, brackets, and the surrounding mechanism for the actual environment.
