VERSATILE. SCALABLE. SIMPLE.
The MRA-RTU-1i is a precision linear actuator engineered for horizontal motion control in industrial robotic systems. Built on a single-axis platform, it features an integrated rack-and-pinion drive mechanism for consistent speed and torque across extended travel distances. Its aluminum extrusion base and steel carriage construction provide structural rigidity, while modular mounting options support various motor and gearbox configurations. Designed for high-cycle applications, the MRA-RTU-1i ensures dependable operation with minimal maintenance requirements.
