SS350 Deepwater Rotator Assembly is a Powerful robotic Positioning Device

SS350 Heavy Duty Rotator

SIDUS Solutions’ SS350 deepwater heavy duty rotator assembly is a powerful robotic positioning device delivering accurate positioning performance.

Users have the option of 3 operating depth configurations; up to 100 ft (30 m) air filled, up to 10,000 ft (3000 m) with internal compensation and up to 20,000 ft (6000 m) with external compensation.

Within a small footprint, you are now able to position heavy loads with ease and high accuracy. Like the SS109, the SS350 gains its dependability and ease of maintenance through integration of DC stepper motors, extremely low backlash harmonic drives and precision ball bearings into a unique modular motor assembly.

This workhorse offers impressive torque ratings up 65 ft-lbs securely locked into the corrosion resistant, one-piece underwater housing. The SS350 subsea heavy duty rotator’s distinctive modular design simplifies field repair to using only small hand tools.

Modifications can be made to include feedback circuits and limit switches for applications where rotational information is vital. Optional Position Limits:   +/-170˚ (other configurations available)
