This Calculator is based on the physics calculations our in-house team use every day; So, we decided to simplify it and make it available to everyone. If this calculator does not cover your application please, email us any diagrams, sketches, etc. and we will be glad to help.

Yes, a FIRGELLI actuator can replace your old actuator. FIRGELLI offers a wide range of electric linear actuators with various specifications, including stroke length, force capacity, and mounting options. Before making a replacement, it's essential to consider the following steps:

Compatibility Check: Compare the specifications of your old actuator with the FIRGELLI actuator you're considering. Ensure that the stroke length, force capacity, and mounting dimensions match or closely align with your requirements.

Mounting and Connections: Check whether the mounting brackets, attachment points, and connection interfaces of the FIRGELLI actuator are compatible with your existing setup.

Power Supply: Confirm that the power requirements (voltage, current) of the FIRGELLI actuator match your power supply or system specifications.

Control and Feedback: If your old actuator had specific control features or feedback mechanisms, verify that the FIRGELLI actuator provides similar functionalities or offers compatible control options.

Integration: Consider any modifications needed to fit the FIRGELLI actuator into your application. This could include adjusting mounting points, making electrical connections, or programming control signals.

Consultation: If you're uncertain about compatibility or installation, feel free to reach out to FIRGELLI's customer support. They can provide guidance and recommendations based on your specific situation.

Choose the Super Duty actuator by starting with the load, mounting geometry, required speed, stroke length, and safety factor. The 65 lb model travels at 40 mm/s with no load and 30 mm/s at its rated load. Choose it when speed matters and the required force, including your safety margin, stays within 65 lb. The 220 lb and 450 lb models provide more force at lower speeds. All three force options are offered in 12V and 24V. For a proper sizing method, read our guide to linear actuator sizing calculations and use the speed vs force tradeoff calculator.

The 450 lb version uses gearing that trades speed for higher force. This is normal for electric linear actuators: more output force usually means a lower travel speed from the same motor voltage. For a deeper explanation, see Linear Actuator Speed Explained or estimate motion time with the Linear Actuator Travel Time Calculator.

The 65 lb model has a 20% duty cycle; the 220 lb and 450 lb models have a 25% duty cycle. Duty cycle is the proportion of operating time within a run-and-rest period. Allow the motor to rest and cool between movements; these models are not intended for continuous operation. Use the Actuator Duty Cycle Calculator to estimate on-time and rest periods, and read Continuous Actuator Cycling for design limits.

The 65 lb model has an approximate static holding force of 400–450 N (90–101 lbf). This is not a guaranteed brake rating. The 220 lb and 450 lb models have the static force ratings shown in the table. Holding performance depends on load, vibration and orientation. Where unexpected movement could injure someone or damage equipment, use a mechanical lock, brake or independent support.

The Super Duty actuator has an IP66 rating, meaning it is protected against dust and strong water jets, but it is not intended for continuous submersion. Outdoor installs should still protect cables, connectors, and mounting points from standing water and corrosion. For more detail, read the IP Rating Guide for Linear Actuators and Are Linear Actuators Waterproof?.

Yes, but synchronized motion requires feedback control. Because the Super Duty actuator includes Hall sensor feedback, it can be used with a compatible controller to keep multiple actuators moving together. For design guidance, read Linear Actuator Synchronization, or see the Synchronous Control Board.

The Hall sensor sends pulse signals as the actuator moves, allowing a controller to track position, compare movement between actuators, and stop or correct motion more accurately than a basic two-wire actuator. This is useful for synchronization, repeatable positioning, and controlled automation systems. Read Feedback Options for Linear Actuators and Electric Linear Actuators with Feedback Sensors.

The feedback accuracy depends on the actuator model, pulse count, controller, calibration, load, and mechanical play in the application. Hall feedback is very useful for tracking relative position, but the complete system should be tested if exact repeatability is required. Use the Linear Actuator Feedback Drift Calculator and the Hall Sensor Spacing Calculator for related calculations.

For basic extend and retract control, the actuator direction is changed by reversing polarity to the motor wires. This can be done with a suitable rocker switch, relay setup, or controller rated for the actuator current. Always confirm the wiring diagram for your exact setup before powering the actuator. Start with The Complete Guide: How to Wire a Linear Actuator to a Switch and the Wiring Diagram Generator.

Use a simple switch or relay when you only need extend and retract motion. Use an FCB-1 or FCB-2 style controller when you need feedback, synchronized motion, saved positions, speed control, or more advanced control behavior. For controller selection, read Linear Actuator Control Boxes, use the Controller Headroom Calculator, and review the FCB-2 controller.

Super Duty actuators should be mounted with compatible brackets that allow the actuator to pivot as the mechanism moves. Poor bracket alignment can create side load, binding, and premature wear. For bracket and geometry checks, use the Actuator Side Load and Bending Moment Calculator and the Linear Actuator Stroke Geometry Calculator. Compatible brackets include MB17, MB20, and MB21.

Linear actuators are designed to push and pull along their centerline, not to carry sideways bending loads. Side load from poor alignment, long unsupported mechanisms, or off-axis mounting can reduce actuator life even when the axial force rating is not exceeded. Use the Actuator Side Load and Bending Moment Calculator and the Linear Actuator Rod Stress Calculator before finalizing the mount.

Stroke length is determined by the pivot locations, actuator mounting points, opening angle, and required force through the full range of motion. Do not choose stroke length only by measuring how far the door or hatch moves at the edge. Use the Linear Actuator Stroke Geometry Calculator, the Standard Hatch Lift Calculator, or the Top Hinge Door Calculator.

Match the DC supply voltage to the selected 12V or 24V actuator. The 65 lb version draws 1.6 A with no load and 6 A at full load at 12V, or 0.8 A and 3 A at 24V. Contact FIRGELLI to confirm the power-supply capacity for the 220 lb and 450 lb 12V models. The maximum current rating is 4 A for all three 24V force models. Allow margin for startup current and any additional actuators or controllers. Long wire runs can also reduce voltage at the actuator, which may slow motion or reduce available force.
