There are three factors in choosing straight-line navigation
1. Determine the track width
Rail width refers to the width of the slide rail. Rail width is one of the key factors that determine the size of its load
2. Determine the track length.
This length is the total length of the rail, not the stroke. Full length = effective stroke + slider spacing (more than 2 sliders) + slider length × number of sliders + safety stroke at both ends. If a protective cover is added, the compressed length of the protective cover at both ends needs to be added.
Three, determine the type and number of sliders
There are two commonly used sliders: flange type and square. The former is a bit lower in height, but wider, and the mounting hole is a through threaded hole, while the latter is higher and narrower, and the mounting hole is a threaded blind hole. Both have short type, standard type and lengthened type (some brands are also called medium load, heavy load and super heavy load). The main difference is that the length of the slider body (metal part) is different, of course the hole of the mounting hole The spacing may also be different, and most short sliders have only 2 mounting holes. The number of sliders should be determined by the user through calculations. Only one is recommended here: as few as can be carried, and as many as can be installed. The type and quantity of the slide and the width of the slide constitute the three elements of the load.
