Texas Cheng Feng linear slide unit _ _ high quality linear slide bearing unit slider series provided by Cheng Feng Bearing Co., Ltd. Lishui City. Feng Cheng Bearing Co., Ltd. Lishui City (susan1125.b2b.hc360.com/) Zhejiang Jinhua, sliding bearings leader, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Feng Cheng bearing in leadership with the staff warmly welcome all inquiries negotiations to create Cheng Feng bearing a better future. Among linear bearings, and can be divided into many sub-categories, linear bearings specifically what you classify it? We take a look at: linear bearings linear bearings into metal and plastic linear bearing metal, metal linear bearing is a low-cost production of linear motion systems, for unlimited travel with the cylinder axis. Since the ball bearing and the shaft was the point contact, so the use of the load is small. Ball rotation with minimal friction linear slide unit slider, which can get smooth movement precision. Axis applications, from a professional point of view of the centerline axis of the beam, or a symmetry axis of the optical system. Astigmatic axis optical axis can be divided into primary and secondary optical axis of the optical axis. The other angles can be divided into solid-axis linear slide unit slider series, hollow shaft, stainless steel shaft and alternative machining axes. Basic understanding of the optical axis of classification, and now we look at the optical axis applications. Let me talk about the optical axis of the solid shaft, usually we use more industrial robots, or as a professional measuring instruments, medical equipment, precision machine tools, aircraft shafts, pneumatic rams moving parts. Secondly hollow shaft, hollow shaft itself as a lighter, but also can reduce the weight of the equipment, simplifying the advantages of linear sliding unit structure can be measured wire factory direct linear sliding unit inside the hollow shaft, compressed air, can be added to the lubricating oil and hydraulic oil . Stainless steel shaft, is generally used for chemical agents, water and other corrosive substances in the environment, as a measurement part. Finally, through a special machine axis, we have hard chrome plating completed after heat treatment is generally used on all types of automation equipment.
