II. Structural Design​

1. Rolling Elements and Raceways: The bearing is equipped with high-precision steel balls as rolling elements inside. These steel balls undergo multiple precision grinding processes, with extremely low surface roughness and strictly controlled dimensional tolerances within a very small range, ensuring a high degree of consistency. Both the inner and outer rings of the bearing are provided with carefully designed deep groove raceways. The radian and depth of the raceways are accurately calculated and optimized to perfectly match the steel balls. This design allows the steel balls to have a uniform distribution of contact area when rolling in the raceways, which can efficiently disperse the radial loads generated by the operation of the equipment and cope with axial loads to a certain extent. During the operation and stress process of the equipment, the steel balls, relying on their flexible rolling characteristics, smoothly transmit the load through multi-point contact, greatly reducing local wear, thereby ensuring the stability and low-noise characteristics of the bearing operation.​

2. Sealing Structure: The "ZZ" in the model clearly indicates that the bearing adopts a double-sided metal dust cover sealing structure. The dust covers are made of high-quality thin metal sheets through precision stamping process and closely fit on both sides of the bearing. This structure is like a solid defense line, which can effectively block the intrusion of foreign objects such as dust, impurities, and water vapor into the bearing, avoid contamination and wear of the steel balls and raceways, and create a clean and stable operating environment inside the bearing. At the same time, this sealing structure can also well protect the pre-filled high-performance grease inside, prevent its loss and deterioration, significantly extend the lubrication cycle and service life of the bearing, and reduce the maintenance frequency and cost of the equipment.​

III. Performance Characteristics​

1. High-Speed Adaptability: The 6800ZZ deep groove ball bearing achieves an extremely low friction coefficient by virtue of advanced manufacturing processes and the selection of high-quality materials. This characteristic enables it to operate stably under high-speed working conditions, easily coping with the challenges brought by the high-speed operation of the equipment. For example, in small high-speed motors, it can perfectly adapt to the high-speed rotation of the rotor, ensure efficient power transmission, and generate little heat during operation, effectively reducing the risk of equipment failure caused by overheating, and providing a strong guarantee for the continuous and stable operation of the equipment.​

2. Reliable Bearing Capacity: Although the bearing is small in size, through reasonable structural design and the use of high-strength materials, it performs excellently in bearing radial loads. At the same time, it also has a certain degree of bidirectional axial load bearing capacity. In small transmission mechanisms, it can not only stably support the rotation of the shaft, effectively cope with radial forces, but also resist axial forces generated during the operation of the equipment, ensuring that the equipment can work continuously and stably under various working conditions.​

3. Low Noise and Low Vibration: Thanks to the precision processing technology, the 6800ZZ deep groove ball bearing has extremely high matching accuracy between various components. The rolling trajectory of the steel balls in the raceways is stable and orderly, which greatly reduces the generation of vibration and noise. In precision instruments and equipment with strict requirements on the operating environment, such as high-precision measuring instruments, the bearing can ensure quiet operation of the equipment, avoid interference with measurement accuracy due to noise and vibration, and provide a solid guarantee for the accurate work of the equipment.​

VI. Maintenance Points​

1. Lubrication Management: The 6800ZZ deep groove ball bearing is pre-filled with an appropriate amount of high-performance grease at the factory. In normal working environments, there is no need to add grease frequently. However, if the equipment operates in a harsh environment, such as high temperature, high humidity, or dusty conditions, the state of the grease should be checked regularly. Once the grease is found to be dry, discolored, or mixed with impurities, the suitable grease should be replaced in time. When adding grease, attention should be paid to the appropriate filling amount; too much or too little may affect the lubrication effect and normal operation of the bearing.​

2. Regular Inspection: Establish a regular inspection system to conduct visual inspections of the bearing, focusing on checking whether the dust covers are intact and whether there are damages, deformations, or looseness. At the same time, with the help of professional vibration monitors, temperature sensors, and other instruments, real-time monitoring of the vibration and temperature changes of the bearing during operation is carried out. If abnormal increase in vibration or temperature exceeding the normal range (generally, the normal working temperature is 10 - 20℃ higher than the ambient temperature) is found, the machine should be shut down immediately for a comprehensive inspection, conduct in-depth investigation of the cause of the fault, and take timely maintenance or replacement measures to prevent the fault from expanding and avoid more serious damage to the equipment.​

3. Installation Notes: When installing the 6800ZZ deep groove ball bearing, it is necessary to ensure a clean installation environment to avoid any foreign objects entering the inside of the bearing.
