The new Thomson Max Jac® linear actuator is one of the most rugged actuators you can find on the market today.  It incorporates decades of experience Thomson has gained from making linear actuators for the mobile-off-highway market. The Max Jac is built to perform in harsh environments and materials, such as fertilizers, mud, sand, high pressure water, slush, salt water, snow, heat or heavy vibrations - and requires little or no maintenance and service.  Max Jac's design provides both high durability and high performance - delivering high speed, ef­ficiency, and accuracy from a compact envelope. As with all Thomson products, if a standard Max Jac does not meet your requirements, we are happy to design a custom version to match your exact specifications.

Let Thomson Help You Make Your Selection!
