Hydraulics are being replaced by robust roller screw actuators, which offer enhanced power and performance. 

The FT Series actuators from Exlar® use a planetary roller screw mounted inside an extruded aluminum housing. These electric linear actuators are compatible with a wide range of standard motors. Motor mounting and gearing configurations are available to meet the requirements of a wide variety of applications. The standard product is offered in four frame sizes with standard stroke lengths up to 36 inches (914 mm) and a load rating up to 40,000 lbf (177 kN).

Engineered Performance

As with all Exlar roller screw actuators, the FT Series delivers high load capacity, high speed, and exceptionally long life compared to acme and ball screw solutions. At equivalent sizes, under moderate to heavy loads, you can expect the FT Series to deliver up to 15 times the working life of other solutions. Greater power, exceptional durability and a much smaller footprint make the FT series a superior electric alternative to hydraulics.

Other Advantages

  • Versatile design can be used for a range of applications. 
  • Multiple frame sizes and an array of options to address almost any requirement
  • Engineered solution accelerates integration and minimizes downtime

NOTES:
1. Mounting face size, shaft length and other details of particular motors may require special adapters or provisions for mounting. Always discuss your motor selection with your local sales representative.
2. For extended temperature operation consult factory for model number.
3. MAX Std. motor size: FT35: 5.6 inch/165 mm, FT45: 7.1 inch/215 mm, FT60: 7.9 inch/215 mm, FT80: 8.5 inch/300 mm. For oversized motors, contact your local sales representative.
4. Not available with inline motor mount, contact your local sales representative.
5. Application details must be approved for use with an FT80.
6. IP65 environmental sealing option not available.

* Some options are not available with every configuration. For options or specials not listed above contact your local representative.
