2. Ball screw - Wikipedia

   en.wikipedia.org/wiki/Ball_screw

   A ball screw (or ballscrew) is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw.

3. Sudarshan laser-guided bomb - Wikipedia

   en.wikipedia.org/wiki/Sudarshan_laser-guided_bomb

   The ADE won the project for developing an LGB in 2006. The project aimed to develop an advanced laser guidance kit for 450 kg (1000 pound) class dumb bombs to improve their accuracy. [1] The Sudarshan kit incorporates laser guidance developed by ADE for 450 kg (1000 pound) bombs to improve the accuracy of a conventional bomb. [12]

4. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   In some cases, high viscosity grease can be added to linear screw actuators to increase the static load. Some manufacturers use this to alter the load for specific needs. Static load capacity can be added to a linear screw actuator using an electromagnetic brake system, which applies friction to the spinning drive nut. For example, a spring may ...

5. Actuator - Wikipedia

   en.wikipedia.org/wiki/Actuator

   An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.

6. Linear-motion bearing - Wikipedia

   en.wikipedia.org/wiki/Linear-motion_bearing

   A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.. Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms.

7. Leadscrew - Wikipedia

   en.wikipedia.org/wiki/Leadscrew

   A leadscrew (or lead screw), also known as a power screw [1] or translation screw, [2] is a screw used as a linkage in a machine, to translate turning motion into linear motion. Because of the large area of sliding contact between their male and female members, screw threads have larger frictional energy losses compared to other linkages.
