Thomson - MG-B (Movoparts) - Slide Guided, Belt Driven Linear Units

Thomson's Movopart® MG-B rodless actuator, slide guided versions are designed to move light loads at medium application speeds with low friction for precise positioning.  With guided linear motion through a belt drive and a saddle that rides along the top of the actuator to carry the load, this design is ideal for industrial or material handling applications.

The self-adjusting, Cover Band Stretcher extends the life of the cover band, which protects belt and guide from contaminants.


MG-B Features:

  • Modular mounting feet
  • Limit switch brackets mount to T-slot
  • Self-adjusting stainless steel cover band
  • Multiple saddle sizes
  • Single and dual nut support
  • Load holding brake required
  • High moment loading
  • Wash down protection
  • Patented internal self-adjusting prism slide guides
  • Can be installed in all directions
  • Easy T-slot mounting
  • Wash down protection
  • Long travel
  • High speed
