Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often unsupported

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.

Gas compressors and systems are used to circulate gas through a process, enhance conditions for chemical reactions, provide inert gas for safety or control systems, recover and recompress process gas, and maintain correct pressure levels by either adding and removing gas or vapors from a process system.

Ultracapacitors store charges (energy) by physically separating positive and negative charges (unlike batteries which do so chemically).  Very high power densities can be achieved by this method.

CNC controllers are used to control machines and processes. They provide capabilities ranging from simple point-to-point linear control to highly complex algorithms with multiple axes of control. CNC controllers are used to retrofit many types of machine shop equipment.

Ball screws, lead screws, and ACME screws are used to convert rotary motion or torque into thrust or linear motion

Screws are fasteners that consist of a threaded shaft at one end and, typically, a head at the other. They are inserted into solid materials and secured via rotation

Conical and telescopic screw covers are used to protect ball, acme and lead screws from contaminants

Screw machine shops manufacture screws and other turned or threaded parts from barstock made of various materials

Industrial screwdrivers and screwfeeders are automated tools that are used to turn screws while providing close control of screw torque. They can be electric or pneumatic and may include features such as torque feedback and controlled stopping

Ball screw support bearings are designed for use in ball or lead screw applications

Timing screws are helical-screw devices used within automated equipment to advance product at a specific rate and interval of movement

Screw pumps are rotary, positive displacement pumps that have one or more screws to transfer fluids or materials along an axis. 

Lead, tin and low melting alloys (white metals) are non-ferrous alloys used in the manufacture of solder, semiconductor, battery and decorative products

Captive screws are fasteners which remain attached to a panel or parent material, even after they are disengaged from the mating panel or part. They meld with the parent via cold forming, and then fuse with the panel or part into a single entity
