1 FTP Series HIGH FORCE ELECTRIC PRESS ACTUATOR Ideal hydraulic press replacement Industry-leading power density Rugged and reliable Flexible and precise

2 FTP Series High Force Electric Press Actuators Hydraulic Press Replacement Based on planetary rollers screw technology, the FTP Series high force electric press actuators were designed to provide very high force in a small package size making them an ideal alternative to hydraulic cylinders in pressing applications. The FTP offers force density not attainable with more common ball screw based electric actuators, up to 15X the life and 2X the force density in most cases. Programmable and Accurate Attaining any kind of accuracy with a traditional hydraulic solution requires complicated servo valves that are difficult to set up and need frequent adjustment for optimum performance. Once set, changeover to a different part or mode of operation is equally as troublesome. The all-electric FTP Series utilizes commonly understood servo motor technology, offering accuracy, control and flexibility not available with hydraulics. Reliable and Efficient The FTP Series high force electric press actuators allow machine builders to meet the ever-increasing performance demands of their customers while minimizing or eliminating the maintenance issues and downtime associated with traditional hydraulic solutions. Their programmability and flexibility significantly reduces changeover time between production runs enabling smaller batch sizes, and they consume 25% less energy than a typical hydraulic solution. Increase your operational efficiency today by switching to the FTP Series.

4 Standard Gearbox Mount Codes for the FTP (Inline or Parallel - 1:1) Bolt Circle Diameter (mm) Pilot Diameter (mm) Shaft Diameter (mm) Shaft Length (mm) Key Width (mm) Motor Mount Code GRA GRC GTA G8A DEFINITIONS: Maximum Force: Calculated Cubic Mean Load for the application should not exceed this value. (Values are derived from the design capacity of the FT Series actuator and should not be exceeded or relied upon for continuous operation.) Life at Maximum Force: Estimated life that can be expected from the actuator when running at Maximum Force for intermittent periods of time. (Theoretical calculation based on the Dynamic Load Rating of the actuator and using the Maximum Force rating as the Cubic Mean Load.) C a (Dynamic Load Rating): A design constant used when calculating the estimated travel life of the roller screw. Maximum Input Torque: The torque required at the screw to produce the Maximum Force rating. Exceeding this value can cause permanent damage to the actuator. Maximum Rated RPM: The maximum allowable rotational screw speed determined by either screw length limitations or the rotational speed limit of the roller screw nut. Maximum Linear Speed: The linear speed achieved by the actuator when Maximum Rated RPM is applied to the roller screw input shaft

Successful applications include bearing press, stamping, and leak testing. Due to design considerations for the FTP series, the extreme forces are only achievable when extending the main rod. See manufacturer's specifications on page 25 for maximum force ratings for each actuator in the FTP series. For any press force less than the maximum rating, calculate the estimated L 10 life by using the calculation method listed. The press distance must not exceed the maximum rated press distance listed on page 25 If there is an application outside the specifications, please fill in the following table and chart. Send the completed document to cha_applications@curtisswright.com. Exlar s sales engineering team will review the application to determine if Exlar has a solution to meet the requirements.
