High Moment Capacity
Robust bearing support carries heavy loads and sidewall forces alike, so the actuator — not an external structure — absorbs the moment loads your application generates.
Sealed for severe environments
SRS Series hydraulic rotary actuators
A specialty series configured for harsh and corrosive environments — marine decks, washdown, and continuous outdoor exposure.
Overview
Inside the SRS Series
The SRS Series takes the sealed, oil-immersed SungJi architecture and configures it for the harshest operating environments: marine decks, offshore equipment, washdown duty, and machines that live outdoors year-round.
With no grease points to flush out and sealing engineered against dust, rain, and spray, the SRS keeps contamination outside and lubrication inside — the combination that determines actuator life in corrosive service.
Series Benefits
The SJH advantages, in every SRS unit
Long Service Life
Oil-immersed bearings, high-precision assembly, and sealing that keeps out dust and rain add up to actuators that keep working season after season, in the environments that wear competitors out.
No Grease Filling Required
Because the bearings run immersed in oil, they lubricate themselves. No grease points, no lube schedules, no missed maintenance — a real advantage for rental fleets and remote equipment.
Light and Compact
A space-efficient helical gear design with fewer components delivers the same — or more — torque from a lighter, smaller package, freeing up payload and simplifying your mounting envelope.
Free Over-Run Protection
Paired with a counterbalance valve, rotation stops the instant the maneuvering bar stops — no drift, no coasting, and no external brakes to buy, mount, or maintain.
Built-In Overload Protection
The counterbalance valve reacts instantly to external shocks, relieving pressure spikes before they reach your equipment — protecting the actuator, the attachment, and the carrier.
