The ball screw of the ball screw robin fashion cycle are implemented using reverse circulation balls, there are two types of inverter. Cylindrical convex key inverter, its cylindrical portion embedded in the nut, the end of reverse open slot 2. Reverse groove by a cylindrical outer surface and the upper end of a round button 1 is positioned to ensure the alignment thread rolling direction. Oblate insert an inverter, the inverter is generally round flat key inserts linear guide what brand, insert nut embedded in grooves cut at its end open outer contour positioning counter sink with insert blocks. Two inverter comparison, the smaller the size of the latter, thereby reducing the radial dimension of a nut and shorten the axial dimension. But the higher dimensional accuracy grooving the outer contour of this inverter and nut. The picture shows the cover circulation for reference purposes only. Strongly resisted the development of low-quality linear guide CNC bearing industry, as represented by a straight line guide bearing system has been rapid development, and have been used widely, due to the limited domestic manufacturers, some manufacturers cut corners to take the opportunity to reduce their quality of rail principle, to reduce costs, which is commonly known as low-quality products. This product is a certain degree of harm, and if this product will not only affect production and may even endanger the lives and safety of the operator. On the domestic market, domestic or tune today there exist a number of counterfeit and substandard products , and these products have been a replacement appearance, replaced by some well-known brand linear guide, posing as a means not only that today we can say that the level is not poor linear guide, the way is also very numerous, a lot of fake products, there are some quality close to qualifying, But accuracy was not up to the national standard. At present the domestic industry confusion linear guide linear guide surface roughness in place, this is the result of poor quality products are loopholes reasons, but also because of posing bearing in the initial task and will not appear much of a problem, and low cylinder prices linear guide Which is good, so there is a large mall filled bearing space. The past two years the rapid development and product quality improvement driven by domestic enterprises bearing fake businesses to invest in the material, technical, false means of progress to make a good impression posing bearings. But the poor quality linear guide products always can not escape the word poor quality, long-term use of this product will be a little bit of a disadvantage to show up, and some freeloaders linear guides users have to be careful to observe, not because of a little interest, try to choose low-quality products, which can only be condoned for fake encourage more of this negative trend, I hope the relevant departments to seriously deal with poor-quality linear rails.
