VERSATILE. SCALABLE. SIMPLE.
The MSA-SB7 Belt Drive is a compact linear actuator designed for precision motion control 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 positioning. The MSA-SB7 supports user-defined stroke lengths up to 5,610 mm, speeds up to 3,810 mm/s, and repeatability of ±0.05 mm. Corrosion-resistant components and optional washdown-duty or water-resistant configurations ensure reliable performance in demanding environments.
Each belt drive 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.
