The ball screws come with instructions and can come either way.
Not all of them coem fully assembled. You can indeed buy them that way but you need to check where you buy it from to see how it comes.
Ball screw actuators are used in industrial equipment where precision motion is required. The ball screw assembly rotates the part using the actuator as a pivot.
shop.ebay.com is the website where the best deals are available on ball screw actuators. business.com is one more reliable option for it. The cheapest I found is $195.58 new at Go2marine. It's a Replacement XDS Actuator, 2-1/4" Stroke. http://www.go2marine.com/product.do?no=163502F&WT.mc_id=gb1
There are many various types of screw jacks and mechanical actuators. Examples include metal screw jacks, rotating screw jacks, inverted screw jacks and vertical screw jacks.
You can purchase a rotary screw compressor from the Compressor World website. Alternatively, you can also purchase this item from the BuyQuincy website.
Someone can purchase a nose screw from a number of online retailers such as amazon. Amazon has a large selection of nose screws from a number of different manufacturers.
If it assembled into a tapped hole, it is a screw. It is tightened (torqued) at the head. If it used witha nut, it is a bolt. It is tightened (torqued) at the nut. Otherwise, it is the same piece of hardware, only the use is different
There are many websites where you can purchase ball screw nuts. A few of these sites include www.homedepot.com, www.lowes.com, and even www.amazon.com.
An actuator is the mechanism by which an agent acts upon an environment. The agent can be either an artificial intelligent agent or any other autonomous being (human, other animal, etc). A mechanism that puts something into automatic action is called an actuator. Some examples of actuators of these various agents include: * Human - Arms, hands, fingers, legs * Part picking robot - Grasping mechanism, moving parts. Examples include solenoids and voice coil actuators. * Mail transfer agent - Update software In engineering, actuators are a subdivision of transducers. They are devices which transform an input signal (mainly an electrical signal) into motion. Electrical motors, pneumatic actuators, hydraulic pistons, relays, comb drive, piezoelectric actuators, thermal bimorphs, Digital Micromirror Devices and electroactive polymers are some examples of such actuators. Motors are mostly used when circular motions are needed, but can also be used for linear applications by transforming circular to linear motion with a bolt and screw transducer. On the other hand, some actuators are intrinsically linear, such as piezoelectric actuators. In virtual instrumentation actuators and sensors are the hardware complements of virtual instruments. Computer programs of virtual instruments use actuators to act upon real world objects. Pressure Switch A pressure switch is an instrument that automatically senses a change in pressure and opens or closes an electrical switching element when a predetermined pressure point is reached
This mechanism, used to move liquid or granular materials, can be sourced direct from the manufacturer, for which the product is named, called Screw Conveyor Corporation.

The job of a screw is to fasten objects together by creating a mechanical bond between them. Screws are used to securely join materials such as wood, metal, or plastic by rotating them into a pre-drilled hole or threaded insert. This provides a strong and stable connection that can be easily assembled and disassembled when needed.
One could purchase plastic screws at hardware stores such as Home Depot or Lowe's. One could also purchase these objects online and have it shipped to their house.
