Kristianstad, Sweden – Regal Rexnord linear motion control solutions brand, Thomson, has introduced key enhancements to its H-Track electro-hydraulic actuator, making it more resilient in harsh and high-moisture environments. The latest version features marine-grade 316 stainless steel components for improved corrosion resistance and a sealed motor housing that enables underwater operation, expanding its suitability across marine, agricultural, industrial and off-highway applications. A refined design and optimised online selection tool further improve product availability and ease of integration.

“The industries we serve push equipment to its limits, often in environments where exposure to moisture, salt and debris is unavoidable,” said Anders Karlsson, Senior Product Manager - Linear Actuators at the Linear Motion Division of Regal Rexnord. “The H-Track has been a trusted solution for demanding applications and with this latest evolution, we are not just entering the marine sector, we are raising the standard for durability across all rugged applications.”

Designed to withstand harsh environments

The Thomson H-Track’s robust, self-contained hydraulic system has always provided the power of hydraulics without the need for hoses, external pumps or regular maintenance. The latest enhancements make the actuator more reliable in applications where conventional models may degrade over time. The latest upgrades include:

• Corrosion-resistant construction – All exposed fasteners, adapters and the piston rod are now 316 stainless steel, a material widely used in marine settings for its high resistance to rust and oxidation. Unlike coated steel, which can deteriorate over time when coatings are scratched or worn, this stainless steel provides lasting durability in saltwater, humid and corrosive conditions.
• Certified for long-term exposure – The H-Track has passed a 2000-hour salt spray test, significantly outperforming typical industry standards.
• IP68 dynamic rating for underwater operation – A newly sealed motor housing allows the H-Track to function while fully submerged, expanding its application range to marine automation, offshore equipment and other water-immersed systems.

Smarter design, faster lead times

Thomson has optimised stroke length and load configurations, making the H-Track easier to specify and faster to deliver. While the design has been refined for manufacturability, it remains fully customisable to meet specific application needs.

H-Track continues to serve as a powerful alternative to traditional hydraulic systems, integrating the pump, motor and cylinder into a single, maintenance-free unit. Its compact design eliminates external hoses and reservoirs, providing high power density and shock-load resistance while also simplifying installation.

“Our focus wasn’t just on marine applications—it was on making a more durable, long-lasting actuator for all rugged environments,” added Karlsson. “This upgrade allows customers across industries to get more reliability, less downtime and a streamlined ordering process, making it easier to integrate into their equipment.”
