SGA-120

The **Bruce SGA-120** represents a precision rotary drilling head engineered for deep foundation projects demanding reliable torque delivery and speed control. This rotary-head unit combines dual-chamber motor technology with a maximum displacement of 150×2 cc/rev, delivering consistent power across variable operating conditions. Its adjustable output speed range of 0–23 rpm provides operators with fine control for different drilling applications, from initial bore setup to final hole completion. Featuring a robust output torque rating of 6 ton.m, the **Bruce SGA-120 specifications** accommodate mid-range foundation drilling operations without compromising structural integrity. The system operates optimally at 300 bar pressure, a standard industrial pressure level that balances efficiency with equipment longevity. This pressure requirement makes the rotary-head compatible with standard hydraulic power plants commonly found on foundation rigs and specialized drilling platforms. The Bruce SGA-120 excels in applications requiring precise rotational control and sustained torque performance. Its modular design facilitates quick installation on existing drilling masts, while the wide speed range enables adaptation to varying soil conditions and drilling depths. Contractors selecting this **Bruce SGA-120** unit gain a versatile attachment that enhances both productivity and precision in deep foundation work.
