VERSATILE. SCALABLE. SIMPLE.
The MSA-R6S Belt Driven Actuator is a compact linear actuator designed for precision motion in light-duty industrial automation and gantry systems. It features an extruded aluminum body with T-slots for flexible mounting and a zero-backlash belt-to-pulley system for smooth, accurate operation. The MSA-R6S supports user-defined stroke lengths up to 3,810 mm, speeds up to 1,905 mm/s, and repeatability of ±0.05 mm. Corrosion-resistant components and optional washdown-duty or water-resistant configurations provide reliable performance in demanding environments.
Each belt driven actuator can be supplied with T-slot sensors, gearboxes, or motor mounting adaptors upon request. Cable track is available upon request. For travel requirements over standard values, contact Macron Dynamics for assistance.
These are standard specifications, if you need a custom configuration, please use our custom configuration request form.
