The LM/LRM Posi-Drive™ stages offer a .168" diameter .125" lead screw, an anti-backlash nut and a flexible zero backlash coupling that accepts a Sigma Mini Servo MS10 motor. They provide a load-carrying capacity of up to 15 pounds. The stages are available in a travel length of .75".

Mini linear actuators measure approximately 1"H x 1"W making them among the smallest commercial available lead screw driven actuators. An inline lead screw with an anti-backlash nut drives the carriage. A beamed coupling and motor mount are included to render the stage ready for the addition of motor and controller.

The new positioners ore available with either linear ball or crossed roller slides. 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.

Isotech can also provide special configurations, motor mounts, hand crank actuation and a variety of leads and pitches.
