Exlar FT Series force tubes use a roller screw mounted inside a telescoping tube mechanism. The follower is attached to the moveable force tube, which then extends and retracts as the screw rotates. The FT Series is designed to be compatible with a wide variety of standard motors. Motor mounting and gearing configurations are available to
meet nearly any application's requirements. The standard product offering includes three frame sizes with strokes from 12 inches to eight feet. The continuous duty thrust load rataing is 2,000 to 20,000 lbf with a peak load rating up to 40,000 lbf.
High Load Capacity, Long Life
As with all Exlar's roller screw products, the FT Series force tubes provide high load capacity, high speed capabilities and exceptionally long life when compared to other actuator technologies, such as acme or ball screws. Other comparably-sized screw actuator products on the market - specifically ball screw and acme screw actuators - have relatively low load capacities, short working lives and limited speed capabilities. At equivalant sizes, under moderate to heavy loads, it is reasonable to project that FT units will deliver up to 15X the working life of those other designs. For OEM designers, this often means much more power and durability can be achieved from a much smaller footprint when Exlar FT units are used.
