Max Jac Linear Actuator
The new Thomson Max Jac® linear actuator is one of the most rugged actuators available today. It incorporates the decades of experience Thomson has gained from making linear actuators for mobile-off-highway applications. The Max Jac is built to perform in harsh environments where materials, such as fertilisers, mud, sand, high pressure water, slush, salt water and snow are present, and withstands heat or heavy vibrations . Max Jac’s design provides both high performance and durability – delivering high speed, efficiency, and accuracy in a compact unit.

* Strokes possible for ball screw models only
** The static force (i.e. backdriving force) for a ball screw unit varies – based on # of cycles run and loading
*** For ballscrew actuators with 100 mm stroke, avg load of 500N and changing load direction
