Linear Actuator Force Calculator: Determine Thrust & Load

Calculate Your Linear Actuator's Required Force

The total mass the actuator needs to move.
Angle of the surface from horizontal (0° for flat, 90° for vertical).
Static or kinetic coefficient of friction between surfaces.
Optional: Acceleration required to move the load. Enter 0 for constant velocity or static holding.

Precisely calculate the required force for linear actuators in your engineering designs. This online tool helps engineers and hobbyists determine the necessary thrust to overcome load, friction, and gravity on inclined planes, ensuring optimal actuator sizing and performance for any application.

Formula:

The required force (F) for a linear actuator to move a load is calculated using the formula:

F = m * (a + g * (sin(θ) + μ * cos(θ)))

  • F = Required Force (Newtons)
  • m = Load Mass (kilograms)
  • a = Desired Acceleration (meters/second²)
  • g = Acceleration due to Gravity (approx. 9.81 m/s²)
  • θ = Angle of Inclination (degrees)
  • μ = Coefficient of Friction (unitless)
