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. The emergence of a different axis, the life we ??are talking about the optical axis, generally used on the optical axis are industrial machinery, like a linear axis, hollow axis and so on. As they have different name, a different axis has its different uses. Some used for hydraulic and pneumatic, engineering machinery, automobile manufacturing rod, plastic machinery rod guide pins, rollers speed linear packaging machinery, printing machinery, bearings, textile machinery, transportation machinery, as well as for some of the major types of electronic Equipment / guide rod linear bearing rails, shafts, pillars, the other places like textile, die-casting machines, injection molding machines, slip devices also have a good application of linear bearings, but overall, because they wear resistance , rust, high precision, good strength and other characteristics, in the machinery industry is very active. Square linear guide rail and circular rail into two types. Circular rail is the earliest linear bearings wholesale products, but poor compared to the square rails accuracy. However, the circular rail is ideal for vertical movement of heavy loads of occasions. Which linear guide should be determined according to the specific use of the actual application requirements rail. Square rail design requirements inherent in the various grinding leads to the initial cost is several times round the guide rail, but with the performance of the linear guide manufacturing technique is superior to the circular guide rail. In general, a square having a higher load capacity of the rail, the precision and rigidity and longer lifetime.
