How can VAV Linear Guide Bearings reduce losses

When the event part of the machine tool is moved, the steel ball moves back and forth in the bracket groove, and the wear of the bracket is distributed to each steel ball so as to extend the operating life of the linear guide bearing. In order to eliminate the gap between the bracket and the rail slider , preloading can advance the stability of the rail system and obtain preload. An oversized steel ball is placed between the guide rail slider and the bracket. The ball diameter tolerance is ± 20 μm. In 0.5 μm increments, the steel balls are sorted and classified and loaded on the guide rails. The amount of preloading depends on the force inducted on the steel ball. If the sense of force on the steel ball is too large and the preloading time is too long, resulting in an increase in the resistance of the stent movement, a balanced and contaminated moving title will appear. To reduce the sensitivity of the forward system, the resistance of the obstruction should be reduced correspondingly. Preloading, and in order to maintain the accuracy of the advancement and accuracy of the preserving, there are enough pre-negative demand, which is contradictory two aspects.

Linear guide bearing installation, should pay attention to the direction and position, linear guide bearings used for a long time, there will be varying degrees of wear, the ball on the force will weaken, this time we must replace the guide rail, linear guide bearing Installation and maintenance, should pay attention to methods, linear guide bearings should be installed on the plane, you can achieve better results, this is more suitable for component sliding, using linear guide bearings, you can do a lot of work.
