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

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.
