Why should deep groove ball bearing 63 series be cleaned during installation

During the installation of deep groove ball bearings 63 series, cleaning is a crucial link, which is directly related to the performance and service life of the bearings. The main purpose of cleaning is to remove grease, dirt and other external impurities that may exist on the inner and outer rings and rolling element surfaces of the bearings. Although these tiny residues may not necessarily affect the function of the bearings under normal circumstances, if they are not completely removed during the installation process, they will gradually cause wear as the bearings run, thereby affecting the overall performance of the bearings.

In deep groove ball bearings 63 series, the matching accuracy between the inner and outer rings and the rolling elements is extremely high. Any tiny impurities may destroy this precision structure, resulting in a decrease in rolling performance, and even abnormal vibration and noise. This uneven wear not only affects the operating efficiency of the bearings, but may also lead to a decrease in bearing accuracy, and even failure in severe cases. Especially in mechanical equipment with high-speed operation and high-precision requirements, bearing cleaning is particularly important. Even tiny impurities may cause serious performance problems, thereby affecting the stability and accuracy of the entire system.

Another important purpose of cleaning bearings is to prevent the intrusion of contaminants. Even if the bearing has undergone preliminary cleaning, external contaminants may still enter the bearing during the actual installation process if the sanitary conditions of the installation environment are not up to standard. Dust, oil and other substances in the air may adhere to the bearing surface during the installation process. If they are not cleaned in time, these contaminants will enter between the raceway and the rolling element as the bearing rotates, causing surface scratches and corrosion. In high temperature, high humidity or chemically corrosive environments, the impact of this contamination is more significant, so cleaning is particularly important.

In addition, the cleaning of deep groove ball bearing series 63 is closely related to the lubrication of the bearing. The role of lubricants is to reduce friction and wear and maintain normal rotation performance. During the cleaning process, it is necessary not only to remove impurities on the bearing surface, but also to provide a suitable environment for the lubricant. If there is dust, grease or other contaminants on the bearing surface, these substances will affect the distribution of the lubricant and even cause uneven lubrication, which in turn affects the smooth operation of the bearing. The combination of lubricants and impurities may form abrasive particles, accelerate the wear of the bearing and shorten its service life. Therefore, it is crucial to thoroughly clean the bearing before installation to ensure that the lubricant or grease can fully cover all moving parts and achieve the best lubrication effect.

Cleaning can also avoid secondary contamination caused by improper operation of tools or operators during installation. When installing deep groove ball bearings 63 series, operators may use press tools, cleaning tools, etc. If these tools themselves are not clean, or if they are improperly operated during operation, unclean substances may be introduced into the bearings. Therefore, cleaning work must be carried out throughout the entire installation process to ensure that every link meets standard requirements. Through comprehensive cleaning measures, the failure rate of bearings can be effectively reduced and the overall operating efficiency and reliability of mechanical equipment can be improved.
