6804 Thin Wall Ball Bearing 6804 Miniature bearings, high-speed low-noise bearings, silent bearings, special bearings for medical devices

Product Description

The rolling elements inside the bearing are high-precision steel balls, also made of high-carbon chromium bearing steel. After multiple fine grinding and polishing processes, the roundness of the steel balls is almost perfect, and the dimensional accuracy reaches the micron level. When the bearing is running, the many evenly distributed steel balls are like a well-trained team, quickly and accurately distributing the load to the inner and outer ring raceways. In the face of radial loads, the steel balls rely on their own high precision and good mechanical properties to efficiently transmit the force, effectively avoiding the phenomenon of local stress concentration, ensuring that the bearing can operate stably and reliably under various complex working conditions, and greatly improving the bearing's load-bearing capacity and service life.

Features of 6804zz Deep Groove Ball Bearing

Strong versatility: The 6804ZZ bearing is designed in strict accordance with international standards. Its specifications of 32mm outer diameter, 20mm inner diameter and 7mm width make it a highly versatile bearing in the industrial field. This standardized size design allows it to be easily and seamlessly matched with various mechanical components. Whether in the compact structure of small motors and instruments, or in some mechanical equipment with strict requirements on space layout, it can be easily installed and used without complex customization or modification, which greatly reduces the design cost and maintenance difficulty of the equipment, and significantly improves the overall compatibility and interchangeability of the equipment.

Excellent speed performance: Thanks to the extremely small friction coefficient between the rolling element and the raceway, and the careful optimization of the internal structure, the 6804ZZ bearing has excellent speed performance. Under suitable lubrication conditions, its limit speed performance is outstanding. When grease lubrication is used, the limit speed can reach 20000-22000r/min. If oil lubrication is used, the limit speed can be further increased to 25000-28000r/min. This excellent speed performance enables it to fully meet the operation requirements of equipment with extremely demanding speed requirements, such as high-speed motors and precision machine tool spindles. During high-speed rotation, it always maintains a stable operating state, effectively reduces the generation of vibration and noise, and provides reliable guarantee for the efficient operation of the equipment.

Considerable load-bearing capacity: With high-quality materials and scientific and reasonable structural design, the 6804ZZ bearing has a strong load-bearing capacity. After professional mechanical calculations and actual tests, its basic rated dynamic load can reach 3.10kN, and its basic rated static load is 2.05kN. This means that it can withstand a certain scale of radial load and a certain degree of axial load. In various types of mechanical equipment, when facing light to medium load conditions, such as the transmission parts of electronic equipment and the power output parts of small machinery, the 6804ZZ bearing can rely on its own load-bearing advantages to stably support the operation of the equipment, ensure that the equipment works normally under the corresponding load conditions, and is not prone to deformation, damage and other faults, which effectively improves the reliability and stability of the equipment.

Low noise and low vibration: Throughout the manufacturing process, high-precision processing of each component and strict quality control make the 6804ZZ bearing exhibit extremely low noise and vibration levels during operation. This low noise and low vibration feature is particularly critical in noise-sensitive equipment application scenarios, such as printers and copiers in office equipment, and some precision testing instruments in medical equipment. Low noise operation not only creates a quiet and comfortable working environment for users, but also low vibration helps to improve the processing accuracy and detection accuracy of the equipment, ensuring that the equipment can accurately complete various work tasks and significantly improve product quality and service levels.

Long service life: From the careful selection of raw materials to every link of the manufacturing process, the 6804ZZ bearing aims to achieve an ultra-long service life. High-quality bearing steel, precise processing technology and efficient and reliable sealing structure work together to enable the bearing to operate stably under various complex and harsh working conditions, effectively resisting common failure forms such as wear, fatigue and corrosion. Under normal use and reasonable maintenance, its service life can reach thousands of hours or even tens of thousands of hours, which greatly reduces the maintenance and replacement frequency of equipment, reduces the overall operating cost of equipment, improves production efficiency, and creates higher economic benefits for the enterprise.
