The Eliminator HD™ Heavy Duty ball screw linear actuator provides a strong, durable, and precise linear motion actuator for industrial automation.
The Eliminator HD™ ball screw actuator converts the latest motor technology into high load, high speed, and high accuracy linear motion. Eliminator HD™ replaces hydraulic and pneumatic linear actuators, cams, levers, and linkages, with controllable motion, repeatable position, and easy adjustment.
E-DRIVE Design, Incorporated has shown consistent success in the toughest applications, e.g. High loads, high speeds, high precision, and extreme durability. Precision ball screw systems, tailored for maximum life, load and speed, provide the motion while fully enclosed, thus eliminating contamination related failures. A long bronze nose bearing provides support for the extended piston. Rugged bronze keys in opposing steel slots provide anti-rotation and counter the tangential forces created during high speed, high frequency, and high load operation.
While other actuator designs force a particular motor decision, the Eliminator HD™ is designed to suit virtually any motor, gear box, or gearhead the customer chooses to use. In-line as well as parallel offset configurations are standard with 1:1 and 2:1 synchronous gearbelt ratios available.
Dual, nonferrous dovetail switch tracks provide a simple method of placing and adjusting switches for over travel protection as well as "home" detection. Hall effect type limit switches are available.

These stages feature exceptionally long life without the need of adjustment, lubrication or maintenance. The integration of a splined linear guide and leadscrew results in a torsionally stiff stage that can be operated in either a horizontal or vertical axis. These stages are ideal for: Pick-and-place, parts transfer, water jet cutting, laser cutting and laser etching, inspection, testing, packaging, and assembly applications. Designed for loads up to 100 lbs. (45 Kg) and speeds to 30 in/sec. (762 mm/sec) the stages can be specified in compound multi-axis configurations such as an X-Y-Z axis gantry robot. To suit the requirements of an application a variety of stepper motors, DC brush and brushless motors, or AC motors can be mounted to the stage. Options to enhance performance and ease integration into a new or existing application are: Custom drilled and/or tapped holes in the stage and/or carriage, end of travel limit switches which can disable the amplifier, linear encoder, cable carrier, and protective bellows.
