10x30x9 Deep Groove Ball Bearing High Precision 6200 Ball Bearing For Small Machinery / Equipment
6200 Deep Groove Ball Bearing 10mm ID 30mm OD 9mm Width for Small Machinery
The 6200 bearing is a widely used deep groove ball bearing. With its excellent comprehensive performance, it plays an important role in various mechanical transmission systems and is a common basic component in industrial production.
Product Structural Design
  • Rolling Elements and Raceways: High-precision steel balls are used as rolling elements. These steel balls undergo fine grinding, resulting in extremely low surface roughness and minimal roundness error, ensuring smooth rolling within the raceways. The inner and outer ring raceways are designed in a deep groove shape, and the raceway curvature is precisely matched with the size of the steel balls. This enables uniform contact between the steel balls and the raceways, effectively dispersing the stress generated by loads and enhancing the bearing's load-carrying capacity and service life.
  • Cage: Mostly made of high-quality steel plates through stamping, it has a lightweight structure and good toughness, which can accurately guide the movement trajectory of the steel balls, avoiding collision and friction between them. During high-speed operation, it maintains a stable state, ensuring low noise and high stability of the bearing. Some models also use nylon cages, which have better corrosion resistance and self-lubricating properties.

Material Selection
  • Bearing Steel: The inner and outer rings and steel balls are made of high-quality bearing steel. After strict heat treatment, their hardness reaches HRC60-65, providing excellent wear resistance, high strength, and good toughness. They can maintain shape stability when bearing loads, resist wear and deformation, and ensure long-term stable operation of the bearing.
  • Cage Material: Steel plate cages are made of high-quality steel plates through stamping, with good stamping performance and strength; nylon cages have better corrosion resistance and shock absorption, suitable for different working environments.
Performance Advantages
  • Low Friction Resistance: The high-precision fit between the rolling elements and raceways, combined with excellent lubrication performance, results in extremely low friction resistance of the bearing. This can improve the efficiency of power transmission in equipment and reduce energy loss.
  • High-Speed Adaptability: The precise structural design and selection of high-quality materials enable the bearing to adapt to relatively high-speed environments. During high-speed operation, the steel balls and cage move stably without obvious jumping or jamming.
  • Compact Structure: With small dimensions, it is suitable for equipment with limited installation space. In small mechanical transmission systems, it can save space while ensuring reliable supporting and transmission performance.
  • Easy Maintenance: It has a simple structure, is easy to install, and has good sealing performance (some models with sealing covers), which can effectively prevent dust and impurities from entering, reduce the number of maintenance times, and lower maintenance costs.
Application Fields
It is widely used in various small machinery and equipment, such as small motors, electric tools, household appliances (e.g., fans, washing machines), medical equipment, office equipment (e.g., printers, copiers), toys, etc. In the transmission components of these devices, the 6200 bearing ensures the normal operation of the equipment with its stable performance.
Installation and Maintenance Points
  • Installation Points: The installation environment must be kept clean to prevent dust and impurities from entering the bearing. The fit accuracy between the shaft and the bearing housing is crucial; it is recommended to select shaft tolerance m6 and bearing housing bore tolerance J7 for a good fit. Professional tools should be used during installation; avoid directly striking the bearing.
  • Lubrication Points: Select appropriate lubricants according to working conditions. For general working conditions, NLGI Grade 2 lithium-based grease can be used, with a filling amount of 1/3-1/2 of the internal space of the bearing. For high-temperature, high-speed, or heavy-load working conditions, it is recommended to use synthetic lubricating oil and equip a complete lubrication system.
  • Maintenance Points: Establish a regular maintenance system, and timely detect potential faults through vibration detection, temperature monitoring, and other means. Generally, it is recommended to conduct vibration detection once a week and temperature monitoring once a month. If abnormal vibration or excessive temperature of the bearing is found, shut down the machine immediately for inspection.
In conclusion, the 6200 bearing, with its excellent performance, compact structure, and wide applicability, has become an ideal choice in the field of small mechanical transmission, providing strong support for the stable operation of various equipment.
