Lightweight Linear Underwater Actuators for Robotics and Projects

Force output varies by model. The Self-Compensated actuator delivers 1,000–1,500 N (220–330 LBS), the Trunion 1000N scales from 1,000 N up to 77,500 N, and the 60,000 N Force model provides up to 50,000 N of axial force — covering a wide range of light-duty robotics to heavy subsea valve actuation applications.

The actuators are constructed from Stainless Steel 316 (SST 316) or Titanium, both of which offer excellent corrosion resistance in harsh marine and saltwater environments. Titanium is recommended for the most demanding deep-sea applications where weight minimization and maximum corrosion resistance are critical requirements.

The Self-Compensated model features integrated RS422 (RS485 duplex) and RS232 serial communication at 19200 baud, enabling standalone position control. The Trunion 1000N and 60,000 N Force models use an external rotary resolver for position feedback and require a separate driver and control logic system for operation.

Yes — the Self-Compensated Linear Actuator features a 30-bit absolute multi-turn encoder mounted on the output shaft, with 14-bit resolution per turn and a 16-bit turns counter. Position information is retained between power cycles, which is essential for subsea systems where reboots or power interruptions can occur during deep-water operations.

The Trunion 1000N and 60,000 N Force models use a Seacon underwater connector for reliable subsea electrical connectivity. The Self-Compensated model uses an MCBH8M subcon underwater connector with 8 pins and includes a 12-inch MCIL8F whip, both rated for deep-sea pressure environments.

Yes. PDF drawings and STEP files are available for download for the Trunion 1000N and 60,000 N Force models to assist with mechanical integration. The Self-Compensated model also provides an Interface & Integration Guide, Quick Start Guide, Windows Utility software, Assembly Drawing, and a YouTube video tutorial for setup and RS422 control.
