Del-Tron Precision has introduced the smallest ever member of its Posi-Drive line of stages with a height of only 1.250 inch and a width of only 1.380 inch. The new stages provide the same outstanding 0.0001

inch straight line accuracy per inch of travel and 0.0001 inch repeatability as the existing Posi-Drive line. The new smaller stages also offer a compact, flexible configuration and are adaptable to standard Nema configurations.
The new Posi-Drive stages offer a 0.125 inch diameter .125 lead screw, an anti-backlash nut and a flexible zero backlash coupling that accepts a Nema 14 motor. They provide a load-carrying capacity of up to 40 pounds. The stages are available in travel lengths ranging from 1 inch to 4 inches. Del-Tron also provides special configurations, motor mounts, hand crank actuation and a variety of leads and pitches. The new positioners are available with either linear ball or crossed roller slides and can be configured for one-, two- or three-axis positioning. In the ball slide version, precision steel balls roll in the raceway grooves with contact at four points, enabling load and moment to be carried on all directions. Rolling resistance is extremely low, ensuring smooth and stable operation. Crossed roller slides physically resemble ball slides except for the bearing design. The rollers share a larger contact surface with the rods as compared to the point contact of steel balls. This bearing design allows crossed roller slides to carry larger loads and absorb greater load impacts than equivalent size ball slides.

| Del-Tron Precision began operations in 1974 supplying original equipment manufacturers with the world’s first commercially available subminiature ball slide. Since then, thousands of Del-Tron ball slides have been incorporated into medical analyzing and testing machines, semiconductor processing equipment, computer peripherals, assembly systems, scientific instruments and many other machines. Del-Tron’s modern corporate campus boasts highly automated computer controlled equipment and final inspection of 100% of all products has been Del-Tron’s policy since its inception.
