BG-AUX-RCB is an electro-hydraulic recirculating ball (RCB) steering gear engineered for medium- and heavy-duty commercial vehicles, including trucks, coaches, and city buses.
Combining hydraulic steering force amplification with advanced electronic control, the system provides the durability of conventional heavy-duty steering gears while enabling integration with modern vehicle electronics and safety systems. CAN Bus communication and integrated angle and torque sensing support ADAS functionality, active steering strategies, and future intelligent vehicle platforms.
Designed for demanding operating environments, BG-AUX-RCB delivers reliable steering performance under high axle loads, wide temperature ranges, and severe road conditions, making it an ideal steering solution for commercial transportation and heavy vehicle applications.
