Types of Screw Conveyors | Engineering Guide
Inclined screw conveyors typically operate from slightly above the horizontal position to 45-degrees from the horizontal position. Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors.
Maintaining Control in Vertical Ballscrew Applications ...
The archimedes screw has a perpetual inclined plane. If its vertically placed the water would sluice down the plane. When its leaning over at about a 30° incline, the inclined plane acts as vertical wall. This wall gets drawn up the trough, forcing whatever liquid or slurry is on the upside of the inclined plane uphill.

Vertical Linear Stages - Positioning Systems
PI provides a number of different vertical linear stages, spanning from stepper motor driven stages to piezo-Z flexure nanopositioners. Vertical positioning stages (Z-stages, lift stages, or elevator stages) are used in focusing or precision positioning and alignment applications, and are often mission-critical in high-end industrial and research applications from optics to …
Why can't an Archimedes Screw be used in a vertical position?
Answer (1 of 2): If you search for a picture of one, you will probably see a cutaway diagram that will show why. Mount it vertically and the water will just run to the bottom.

Five things to consider in vertical applications
When using a ball screw or lead screw in a vertical application, the full load is experienced as an axial force, which can cause the screw to bend and, eventually, buckle under the load. The buckling load is determined by the screw's root diameter, unsupported length, and end bearing arrangement.
WHAT IS BACKLASH AND HOW TO CORRECT IT - MachMotion
Backlash with a CNC is the same as taking a screw and threading a nut on to it. Now with one hand hold the screw and the other hand hold the nut and push/pull on the nut. That small amount of movement between the threads is the cause of backlash. Since both the screw and nut threads don't fit perfectly together there is always "Play".

Linear Position and Displacement Measurement | Lion Precision
Using a set-screw in a thru-hole mount only holds the probe at two points – the set-screw and the point opposite the set-screw. The probe is free to rotate in the axis 90° from the set-screw axis. Depending on the width of the surface against which the set-screw pushes the probe, the probe may also be able to rotate along its axis as well.
