Astronomical telescope supporting bearings received high praise, the customer given new products R & D to ZWZ

ZWZ offered three-species supporting bearing to a well-known domestic observatory in 2005. It has been running well and met the customer's technical requirements. And it received high praise.A few days ago, the customer handed over 3 specifications for bearing R & D to ZWZ,including right ascension bearings and declination bearings.

According to the introduction of Chi Haifeng, director of the Heavy Machinery Bearing Research Institute of the Engineering Center, the right ascension bearings and declination bearings are light and thin series new products. The precision requirements are particularly high, and there are technical requirements such as pre-tightening, stiffness, and friction torque. They are difficult to design and process. At present, the Heavy Machinery Bearing Research Institute has completed product design and is about to start production. 

When it developed and produced the first large-scale satellite tracking telescope bearing in China, the company has developed multi-standard astronomical telescope series bearings since 1975. Among them, the telescope bearings used in Antarctic astronomical equipment developed in 2010 are resistant to extremely low temperatures and operating temperatures as low as -80°C, reaching internationally advanced levels. In April this year, the company developed the world's largest radio telescope array SKA antenna supporting the core parts of the bearing.And the product accuracy, use stiffness have reached the international advanced level.
