Fixed element linear guide works of the two linear guide systems (rail) of the basic functions as bearing ring mounted bracket ball shape for "v" shape. Stent wrapped top and both sides of the guide rail. In order to support the work of the machine parts, a linear guide has at least four brackets. For supporting a large working parts, the number may be more than four scaffold. The working parts of the machine when moving linear guides, ball in the bracket groove circulation, to apportion the amount of wear on each bracket to the ball, thus extending the life of linear guides. In order to eliminate the gap between the bracket and the guide rail, preload can improve the stability of the guidance system, the preload is obtained. In between the rail and bracket mounting oversized ball. Ball diameter tolerance is ± 20 microns to 0.5 micron increments, the ball sorting, were loaded onto the rail, the size of the pre-load, depending on the forces acting on the ball. If the forces acting on the ball is too large, subjected to pre-load time is too long, resulting in enhanced resistance to movement of the carriage, there will be balanced by the effect of the problem; order to improve the sensitivity of the system, reducing motion resistance, corresponding to reduce preload and in order to improve the accuracy and precision of movement retention, require adequate pre-negative linear guide rail installation, which is a contradiction in two ways. Principle 4 --- linear guide priority selection of the brand's continued supply capacity rather than a single standard or a single order: Do not believe any manufacturer discounts (see Shanghai certain meters website advertising: New User hit 7 fold) straight rail agency, rail is not soy sauce, no cost difference between brewing and blending. 5 --- Before asking suppliers to determine the model: Do not be too sure manufacturers samples, if you carefully look, probably will see the text on the back cover or seal three lowermost somewhere: "...... this catalog All parameters are for reference linear guide price, we will try to make it right, but can not promise complete and correct. At the same time the company can change without notice. All rights reserved product parameters, "What do you mean? According to this sample you may buy something and not on the same sample, and people can not be held liable. Of course, such a problem in general people will give you change, but the delay time is the user.
