Linear Underwater Actuator Trunion 1000N
- Scalable force: 1,000 N to 77,500 N
- Rated to 6,000 m depth for subsea ops
- Multi-voltage: 24, 48, or 230 VDC input
NV Mechanics Design Ltd. offers high-performance underwater linear actuators engineered for deep-sea and subsea applications. Rated to depths of 3,000–6,000 meters, these brushless motor-driven actuators deliver axial forces up to 77,500 N, with integrated encoders and pressure compensation for reliable operation in extreme marine environments.






The lifespan of an underwater linear actuator depends on operating depth, duty cycle, and environmental conditions. NV Mechanics Design actuators use brushless motors—which have no brush wear—and corrosion-resistant SST 316 or Titanium housings, significantly extending service life in saltwater. Absolute encoders retain position data between power cycles, reducing mechanical stress. Contact the manufacturer for application-specific MTBF estimates.
