CONTACT SALES/SUPPORT

Linear drives from Curtiss-Wright can be used in a wide range of applications and consist of a linear roller screw spindle, transmitting the rotation of the motor linearly. For upgrades and replacements of existing elevation hydraulic drives, an Elevation Linear Gear (ELG) can be easily installed within the available space.

All linear drives are modular where the servo drive and hand crank can be repositioned when location and space restraints require. Dual redundant brakes and a manual backup drive (for use when power is off) are also included for system security.
