G2000A5.7ST: Product OverviewThe G2000A5.7ST is a helical-bevel gear unit from ABB’s mechanical power transmission product range. This industrial gearbox is designed to provide reliable speed reduction and torque multiplication in heavy-duty applications. It features a combination of helical and bevel gearing, making it suitable for applications requiring right-angle power transmission where input and output shafts are oriented at 90 degrees to each other. The gear unit is typically used with electric motors to adapt the motor’s high speed, low torque output to the lower speed, high torque requirements of driven equipment such as conveyors, mixers, agitators, and other industrial machinery.The gear unit is constructed with high-strength cast iron housing, hardened and precision-ground gearing, and heavy-duty bearings to ensure long service life and reliable operation in demanding industrial environments. It is designed for continuous operation with high efficiency and low noise levels. The unit includes features such as integral cooling fins for efficient heat dissipation, high-quality sealing systems to prevent lubricant leakage and contamination ingress, and robust shaft design to handle substantial radial and axial loads.

Core Features & Customer ValueThe helical-bevel gear design provides excellent efficiency and smooth, quiet operation compared to other gear types. The helical gears offer gradual tooth engagement, resulting in higher load capacity and reduced noise levels, while the bevel gears enable efficient 90-degree power transmission. For plant engineers, this translates to reliable power transmission with minimal energy loss and reduced maintenance requirements.The robust construction ensures long service life even in harsh operating conditions. The high-quality sealing system prevents lubricant leakage and protects against contaminant ingress, extending bearing and gear life. The unit’s high thermal capacity allows for continuous operation at full load without external cooling in most ambient conditions. These features result in reduced downtime and lower total cost of ownership over the equipment’s lifecycle.Typical ApplicationsIn mining and bulk material handling, the G2000A5.7ST drives conveyor systems, handling heavy loads over long distances. The right-angle configuration allows flexible installation options where motor positioning is constrained.In water and wastewater treatment, the gear unit drives mixers and aerators in treatment basins. The corrosion-resistant finishes and effective sealing make it suitable for wet and chemically aggressive environments.
