To successfully obtain valuable lunar soil, a series of key core technologies such as surface sampling and drilling are essential. Among them, surface sampling refers to using a robotic arm to carry a sampling device to shovel lunar soil or pick up lunar rocks at multiple positions on the lunar surface; Drilling is the process of using a drill rod to drill into the lunar surface at a predetermined depth and collect lunar soil core samples that maintain the "profile sequence".

On November 12, at the 15th China International Aviation and Aerospace Exhibition held in Zhuhai, Guangdong Province, bearing products with multiple specifications, high precision and tip were presented at the exhibition. Wang Qiyao, Chairman of the Standing Committee of the Dalian Municipal People's Congress, visited the tile axle booth to gain a detailed understanding of the company's reform and development, technological research and development, and other aspects.

1. How to distinguish between heavy bearings and light bearingsActually, these differences are very obvious. Firstly, there is a difference in quality, which is mainly caused by two differences. The first difference is that in many cases, the material of lightweight bearings is different from that of heavy-duty bearings. You must understand this. In order to meet different industrial production or processing needs, bearings must have different performance. The different materials of various bearings are actually due to this reason.Another point is the difference in physical structure.

The high-temperature bearing needs to be replaced and new high-temperature lubricating grease needs to be added. However, this lubricating grease needs to be added just right, whether it's too much or too little won't work. How much does it need to be added specifically?What is the problem with adding too much lubricating grease to high-temperature bearings?Adding too much high-temperature lubricating grease can cause damage to the bearings.(1) Adding too much lubricating grease will increase the friction torque.

The so-called burn damage state of  bearings refers to the rapid heating of the raceway wheel, rolling element, and retainer of  bearings during rotation until discoloration, softening, deposition, and damage occur.The main reason for bearing burns is due to poor lubrication of  bearings, which may have used non-standard lubricants or excessive or insufficient lubricants, both of which are incorrect. Secondly, it may be due to excessive load (excessive preloading). The rotational speed is too high. The clearance is too small. There is water or other foreign objects invading.

On the occasion of the opening of the 2023 Asia International Power Transmission and Control Technology Exhibition, on behalf of the company, I would like toextend a warm welcome to customers and friends from all over the world!

The 2024 South China International Industrial Expo (hereinafter referred to as the South China Industrial Expo), jointly organized by Hanover Milan Exhibition (Shanghai) Co., Ltd. and Donghao Lansheng Exhibition Group Shanghai Industrial and Commercial Exhibition Co., Ltd., will make its debut at the Shenzhen International Convention and Exhibition Center (Bao'an New Hall) from June 19th to 21st.Here, the roar of machines is not only the symphony of steel, but also the rhythm of the leap in intelligent technology.

The linear module affects the operation of many mechanical devices and is also one of the basic elements of the machine. Therefore, the quality of the linear module has a great influence on the operation of the machine. So how can you check the quality of a linear module?

The installation of linear bearings requires a lot of attention to methods. Whether you are installing high-quality imported bearings or domestically produced bearings with average quality, it may affect the service life and performance of the bearings. Therefore, when installing linear bearings, we need to be meticulous and careful during the installation process, controlling every installation detail. If we don't understand the installation technology of bearings, don't blindly install them.1.
