Yangzhou linear guides, Bot Seiko (certified), linear guides provided by Seiko Co., Ltd. Shandong Bot. Seiko Co., Ltd. Shandong Bot (www.jsinfo.com.cn) is specialized in the "ball screws, lead screws, linear guides, spindle" of the enterprise, the company adhering to the "honesty, hard service" concept, for You provide the highest quality products and services. Welcome to inquire! Contact: Zhang complete. Seiko Co., Ltd. Shandong Bot machine when working parts moving in the bracket groove ball circulating Changzhou linear guide, the assessed 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, the preload can improve the stability of the rail system, the preload is obtained. Is in between the rail and bracket mounting oversized ball. Ball diameter tolerance of ± 20 microns to 0.5 microns increments, sorting the balls 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 stent resistance movement, there will be problems balancing role; To improve the sensitivity of the system to reduce the resistance movement, accordingly to reduce preload Zhenjiang linear guide, and in order to improve the accuracy and precision of movement retention, require adequate pre-negative, which is a contradiction in two ways. Design Seiko Co., Ltd. Shandong Bot linear guide systems, and strive to have maximum contact area between the fixed component and a mobile element, which not only can improve the carrying capacity of linear guide systems, and the system can withstand the impact of intermittent cutting or cutting generated gravity force, the force is spread widely, expanding the area of ??endurance. To achieve this, the groove shape of the rail system are varied, there are two representative Yangzhou linear guide, called Gothic (pointed arch), extending in a semicircular shape, the contact point of the apex ; the other is arc-shaped, can also play the same role. No matter what kind of structure, only one purpose, and strive for more contact with the rail rolling ball radius (fixed components). Factors determining system performance characteristics are: how the rolling element contact with the rail, which is the key issue.
