VERSATILE. SCALABLE. SIMPLE.
The MRA-RTU-1 Robot Transfer Unit is a 7th-axis linear actuator designed for precise motion in industrial automation and robotic applications. It features an aluminum cart matched to the robot model and an extruded aluminum actuator body with T-slots for flexible mounting. The MRA-RTU-1 supports user-defined stroke lengths, smooth high-speed travel, and near-zero backlash for accurate, stable positioning. Built with corrosion-resistant components, it provides long-lasting durability and minimal maintenance in demanding environments.
Each RTU can be supplied with T-slot sensors, gearboxes, or motor mounting adaptors upon request. For travel requirements over standard values, contact Macron Dynamics for assistance.
