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. When the machine working member moves, the steel ball circulation groove in the holder, the holder is to apportion the amount of wear on the respective balls, thereby extending the life of the linear guide. 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 big, too long subjected to pre-load ABBA linear guide, resulting in enhanced resistance movement stand, there will be problems balancing role; In order to improve the sensitivity of silver linear guide systems, reducing the resistance movement, Accordingly, to reduce the pre-load, and in order to improve the accuracy and precision of movement retention, requires sufficient pre-negative linear guide, which is contradictory two aspects. Factors contributing to shorten the life of the linear guide analysis almost all machinery products require linear guide to normal operation, there are shows that the linear guide is very important, and the choice of linear guide is also essential, linear guide is to support machine running a small part, this is good or bad part determines whether the machine to work properly, so the choice of the linear guide is also very critical. Faced with major brands of linear guide, most people would be more inclined to linear guides, linear guides are excellent because the world famous, high-quality linear guide also fundamentally ensure longer life more. No matter what, we all want to be able to use more long term, linear guide is also true, but no matter how good the quality of the stuff, if not properly maintained, it is very easy bad. So, in the course of linear guide, there are factors which will affect the life of the linear guide it? Factors affecting the life of linear guides are many, the most important is the influence of external factors. The so-called external factors refer to the demolition installation, maintenance, work environment, making installation and removal when the linear guide, be sure to follow the various installation requirements and considerations to strict operation, once the improper operation, will make linear guide in during operation, causing some damage to the AMT linear guide, thereby shortening the life of linear guides. Do not think of a good quality linear guide, on the lack of repair and maintenance, bearings also need regular maintenance and repair, only usually do maintenance in order to prolong the life of the linear guide. What work environment will affect the life of linear guides, linear guides if working in a hostile environment, it can cause varying degrees of damage to the linear guides and the machine itself will be, if it does not timely maintenance treatment, then, will greatly shorten life linear guide. Want to extend the life of the linear guide, we must first identify the factors that affect the life of the linear guide where, so as to make reasonable improvements targeted to achieve the goal to extend the service life of the linear guide.
