Description

Lim-Tec Underwater Servo Actuator

Fully Sealed & High Precision — Designed for Underwater Robotics, Marine Equipment and Deep-Sea Applications

Lim-Tec Underwater Servo Actuator is a high-precision linear actuator specifically designed for demanding underwater environments. Featuring a fully sealed, pressure-resistant construction, it provides reliable linear motion, precise positioning, and secure locking without the risk of hydraulic oil leakage.
Available in shallow-water and deep-water configurations, the actuator can be customized for different operating depths and application requirements. It is ideally suited for marine engineering, underwater robotics, marine vessels, subsea equipment, and deep-sea operations.

Key Advantages
Designed for long-term underwater operation, providing reliable sealing and preventing water ingress under demanding operating conditions. The shallow-water series offers a cost-effective solution for applications up to 100 m, while the deep-water series is designed for high-pressure and highly corrosive subsea environments. Corrosion-resistant materials provide excellent resistance to seawater, salt spray, mud, sand, and other harsh marine environments. Closed-loop servo control enables precise positioning, stable motion, high rigidity, and smooth operation with minimal risk of stick-slip. Electric actuator eliminates hydraulic oil leakage and significantly reduces maintenance requirements and operating costs. Force, stroke, speed, voltage, mounting configuration, feedback, and communication interfaces can be customized to meet specific underwater equipment requirements.
