Linear Gear Drives

Electromechanical Linear Gear Drives

For Transmission of Linear Movements

Our pre-engineered Electrical Linear Gear (ELG) Drives take the guesswork out of motion control system design. Highly engineered, rugged, and reliable, the ELG line of drives is designed for operation in the most demanding applications and under the harshest conditions.

Linear motion systems are present in a wide variety of defense applications. From combat vehicles to fighter jet carriers to cargo planes, linear motion systems are critical to the safety of personnel and the performance of their equipment.

Curtiss-Wright's linear gear drives are purpose-built for operation in the harshest locations and the most severe conditions. Responsible for linear motion, our linear gear drives are designed to provide the highest degree of precision in complex aiming and stabilization systems.

In addition, as part of our modular suite of rugged and field-proven components, system integrators have the flexibility to choose the product configuration best suited to their application's needs with a streamlined path to upgrade as those needs change.

Perform precision movements reliably with Curtiss-Wright's fully customizable line of linear gear drives.

Highly engineered to meet the unique needs of military applications

While gear drives are commonly used for industrial purposes, special considerations must be made for defense applications. Curtiss-Wright linear gear drives are pre-engineered to meet the most demanding defense program requirements, simplifying the development of critical motion control systems to get you in the field faster. Motion control systems in defense applications are often responsible for the controlled movement of complex systems. These systems can include turret stabilization systems responsible for accurately aiming at a target and stabilizing a shot while speeding over rough terrain and high precision drive systems used to position mobile radar or satellite systems. The ELG line of linear gear drives provides smooth, linear motion even for applications subject to heavy loads, continuous vibrations, and high shock.

Fully configurable for maximum flexibility

The ELG line of linear gear drives is fully customizable, giving system integrators the freedom and flexibility to define and deploy the exact solution they require. Define system performance with different screw pitches and configurable screw stroke while maximizing stiffness and minimizing friction and backlash. Configure torque and access additional safety features with a clutch/brake/no-back combination. No matter the configuration, the ELG line of drives supports military applications' unique needs while still allowing system integrators to create a system that meets their exact specifications.

The latest servo technologies

With complete customization comes the assurance that each linear gear drive configuration will include the latest in motion control technology and is compatible with Curtiss-Wright's latest inertial stabilization technology. ELG drives include a brushless AC servo motor with an integrated high resolution, multiturn, absolute motor feedback sensor. This high torque servo motor packs ultimate performance in a compact package.

Rugged, field-proven design

Curtiss-Wright linear gear drives are designed for operation under extreme conditions, including heavy loads, continuous vibrations, and high shock. As a result, every component undergoes extensive testing to ensure it performs reliably and accurately in the most rugged geographic locations and the most severe weather conditions.
