CubeMars SW7 Underwater Thruster

Product Description

The SW7 underwater thruster is a high-efficiency propulsion unit from CubeMars’ SW series, specifically designed for shallow-water applications such as unmanned surface vessels (USVs) and handheld underwater propulsion systems.

Rated at 36 V with a continuous power output of approximately 360 W, it delivers a maximum thrust of ≥ 7 kgf and is suitable for operation in depths from 0 to 30 meters.

The thruster features a precision-cast aluminum alloy housing, a dual-chamber independent sealing structure, and a low-friction dynamic shaft seal. High-thermal-conductivity potting material is used internally to enhance heat dissipation. Robust, sand-resistant, and virtually maintenance-free, the SW7 is built for reliable underwater performance.
