[Andy Pugh] found himself in need of a large linear slide, so he resorted to making his own with steel square tubing and a bit of PTFE (Teflon). The PTFE slider/spacers [Andy] needed a compact ...

Linear slides and stages provide smooth, precision linear motion and positioning for many different types of automated machinery. They use one of several linear bearing methods to reduce friction, ...

Try that with a linear slider. Granted, this slider is not powered, but given that the axes are synced with timing belts, it wouldn’t be difficult to add a motor. We’ve seen a lot of sliders ...

Slide rules are analog computing devices marked with linear or logarithmic scales, some on a moving slide and some stationary on the base of the instrument, so that two numbers may be added or ...

Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper. They are variable resistors with three leads. Two leads connect to the ...
