Thomson's Movopart® MF-K rodless actuator slides
provide guided linear motion through a ball screw drive and a saddle
that rides along the top of the actuator to carry the load. Available
in two versions: M (single nut) and MD (double nut), these ball guided
units are designed to provide high load capacity with low friction for
precise positioning - able to produce high thrust, high precision,
stiffness, and long stroke capabilities.
The Cover Band Stretcher extends the life of the cover band, which
protects screw and guide from contaminants, and eliminates the need to
adjust the tension as it wears.
