The  electric  spindle is a kind of precision component with high speed and high rigidity. The  spindle  must be used strictly in accordance with the operating specifications, otherwise it will increase equipment failure and shorten equipment life. ZYS BEARING recommends the end user to follow the below rules during use: ⑴ Before starting the machine, first make sure that the spindle cooling system is working properly, and then turn on the electric spindle. It is strictly forbidden to use the spindle without cooling, so we must check whether the fan...

For  industrial robots , accuracy is a very important factor that directly affects product quality and productivity. The main factor affecting the accuracy of industrial robots is the bearings. So what kind of bearings can make industrial robots have higher precision?  1. Design of key structural parameters Industrial robot bearings have the requirements of long life, high rigidity and low friction. Therefore, when designing industrial robots, not only the maximum rated dynamic load should be considered, but also the optimal value of each structural parameter should be carefully selected to improve the contact stress distribution of the bearing parts. Then it can reach the optimum contact state for the formation of the lubricating oil film and improve the service life of the bearing. 2. The raceway position The inner and outer rings of the contact ball bearing of the industrial robot adopt the integral structure, and the general sectional area is only 20% of the beari...

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...
