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

ZYS provides its customers with high quality slew rings within a wide range of sizes used in many applications. Sizes range from 3” (100mm) up to 6 ft (2m) in OD. For design and application purposes, slew rings are available with external teeth on the outer ring, internal teeth on the inner ring, or without teeth. Driving Pinions and Hydraulic Motors are available to mesh with appropriate slew rings upon request. Single row, and double row slew rings are available to accommodate different loading applications. For non-market standard rings, our team of engineers work alongside our customers to provide custom made slew rings as per required performance.

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...

YRT bearing is a slewing mechanism with outer ring rotation and inner ring support. A row of radial rollers ensures that the bearing can bear radial force and overturning moment. YRT bearing consists of a thrust/centrial seat ring and a thrust/radial axis The ring, a thrust washer, two needle roller cage assemblies and a set of centripetal cylindrical rollers. The seat ring and the shaft ring have evenly distributed screw holes for installation. This type of bearing has high axial and radial load capacity. Rotary mechanism suitable for axial load. YRT bearings are mainly used in CNC machine tool manufacturing. As its core components, domestic YRT bearings are still dependent on imports. The accuracy parameter standards of domestic YRT bearings are also based on international manufacturers. Since the beginning of the 21st century, especially with the launch of the national“High-end CNC machine tools and basic manufacturing equipment" project, it has greatly promoted the deve...
