ZYS precision bearing, ball bearings, roller bearings, bearing parts

  Shield machine is a tunnel construction equipment that integrates machinery, electricity, hydraulics, optics, mechanics, pneumatics, sensing, information, and guidance, and can complete construction processes such as excavation, support, and slag removal and perform continuous operation in factory-like assembly lines. The shield machine is known as the "king of construction machinery", and it is a major key equipment to measure the level of a country's equipment manufacturing level. With the comprehensive deployment of shield tunneling construction of urban subways, railway tunnels, highway tunnels, water conservancy engineering, municipal gas pipeline engineering, sewage pipeline engineering, heating and cooling pipeline engineering, and cable pipeline engineering in China, the total market demand for shield machines shows a rapid growth trend, which also brings a broad market to shield machine bearings. The cutter head is a key component of the shield machine and play...

On June 17, with the "China Railway No. 797" cutter head turning slowly, a slurry  shield machine with  diameter of 13.46 meters was officially off line . The slurry  shield machine,  China's first super-large  diameter slurry  shield machine exported to Europe,  will be used in the construction of the Swinoujscie tunnel in Poland. The "China Railway No. 797" slurry  shield machine has a cutter head diameter of 13.46 meters, a total length of about 105 meters, and a total weight of more than 2700 tons. Based on the requirements of customers and in-depth analysis of specific application conditions, Luoyang Bearing Research Institute Co. Ltd. (ZYS) gave full play to ZYS comprehensive technical advantages and developed  slewing bearing s of extra large segment assembling machines for customers. The ZYS bearing product adopts a  four-point contact ball bearing structure , and the bearing inner ring is integrated with high-precision gear...
