H-Track actuators incorporate a patented fluid power design, which provides high load capability for extreme duty use, a more compact pin to pin than other actuators of the same load capability, excellent ingress protection and corrosion resistance. The H-Track uses an external gear pump connected to a reservoir and actuator, yielding the most impact resistant Warner actuator. The H-Track pump is burnished, cleaned, flushed and vacuum filled with degassed hydraulic fluid. The system is completely sealed with no hoses to leak. This ensures you receive contaminant free and maintenance-free product for the life of the actuator.
