SS351 Deepwater Rotator Assembly with Corrosion Resistant 316 Stainless Steel Housing
[addtoany]

SS351 Heavy Duty, Stainless Steel Rotator

SIDUS Solutions’ SS351 deepwater rotator assembly is a powerful robotic positioning device. Within a small footprint, you are now able to position heavy loads up to 150lbs (68kg) with ease and high accuracy. Like the SS109, the SS351 gains its dependability and ease of maintenance through integration of reversible synchronous 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 316 stainless steel housing. Operating depth rated at up to 10,000 ft (3000 m) with internal compensation and up to 20,000 ft (6000 m) with external compensation.

The distinctive modular design simplifies field repair to using only small hand tools.  Communication via Analog, RS-485 or RS-232.

Modifications can be made to include feedback circuits and limit switches for applications where rotational information is vital.  Optional Position Limits:  +/-170° Pan, +/-90° Tilt (other configurations available).
