Vacuum high temperature bearing in the vacuum coating machine

                     

 Vacuum coating machine mainly refers to a kind of need to be done under high vacuum coating, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and so on many kinds. The main idea is divided into evaporation and sputtering.
  We introduced the application of vacuum bearing in evaporative vacuum coating machine, evaporation coating is to heat the surface of target components to form groups of atoms, or ions by evaporation. And subsidence in the substrate surface, through the film-forming process (scatter - island structure - the vagus structure - layered growth) form the membrane. For sputtering coating, can be simple to understand for the use of electronic or high-energy laser bombardment of target, and the surface components form groups of atoms, or ions was sputtering, and eventually deposited on the substrate surface, experience the film-forming process, eventually form a thin film.
  Bearing installation position as shown in the picture the ends of the pipe axis, the internal installation of dozens of similar units. Unbearable because the body temperature is higher, the ordinary bearing several hundred degrees centigrade high temperature vacuum working environment, lubrication grease lubrication, graphite bearing products in the process of operation in high temperature vacuum environment brings grease and graphite dust pollution and scrap bearing a short time at the same time, lead to the unqualified products.
We designed this high temperature bearing, combining with the actual working environment, use high temperature self-lubrication works; Through long-term validation achieved long service life, maintenance free, spotlessness, will not bring pollution, thus to ensure the normal operation of the machine. Product replacement of simple installation, greatly improve the machine running time and efficiency, reducing the machine maintenance frequency and maintenance costs.
