MDC-628

The MDC-628 is a high-capacity linear actuator designed for precision motion control in large-scale industrial automation systems. Featuring a reinforced belt drive and a rigid aluminum extrusion, it delivers accurate, stable travel across long distances at high speeds. Its modular configuration supports multiple motor and gearbox mounting options, allowing for seamless integration into custom multi-axis assemblies. Built with robust aluminum and steel components, the MDC-628 offers consistent performance, low maintenance, and long-term durability in demanding operating environments.

  • Dual Cart Single Axis Belt Actuator.
  • User defined Strokes.
  • Mounting flexibility in any orientation.
  • Extruded aluminum actuator body with T-slots for ease of mounting.
  • Easy to adjust belt tensioner.
  • One piece machined and stress proof shafted pulley.
  • Zero backlash belt to pulley design.
  • Multiple Carts Available upon Request.
  • Can be Made into a centering actuator.
  • Corrosion resistant components.
  • Washdown Duty or Water- Resistant Options upon request.
