Throttle Control Mechanism: These linear motion units can be used in throttle control systems to ensure precise and smooth movement of 

throttle levers.

The linear motion units help in maintaining accurate and responsive control over engine thrust.

Flap Actuation Systems: Aircraft have movable flaps on their wings to control lift and drag during different phases of flight. SBR..UU series 

units can be employed in the actuation systems for these flaps. They contribute to the accurate positioning of flaps, ensuring optimal 

aerodynamic performance.

Aileron and Elevator Control: Ailerons and elevators are control surfaces that enable the aircraft to roll and pitch, respectively. Linear motion 

units play a role in the precise control mechanisms of these surfaces. They assist in the smooth and controlled movement of ailerons and 

elevators, contributing to the stability and maneuverability of the aircraft.

Rudder Control Systems: Linear motion units can be integrated into the rudder control systems to ensure accurate and reliable movement of 

the rudder. They contribute to the aircraft's yaw control, allowing for stable and controlled changes in direction.

Landing Gear Actuation: SBR..UU series units may be employed in the actuation systems of landing gear components. They contribute to the 

precise extension and retraction of landing gear, ensuring safe and reliable landing operations.

Control Surface Feedback Systems: Linear motion units can be used in feedback systems to provide information on the position of control 

surfaces back to the aircraft's control system. This feedback is essential for maintaining control authority and for the implementation of 

fly-by-wire systems.

Autopilot Systems: In autopilot systems, linear motion units play a role in the fine-tuning and adjustment of control surfaces to maintain the 

aircraft's desired attitude and trajectory. They contribute to the overall stability and automated control of the aircraft.
