Material

1. Ring Material: The inner and outer rings of the 682 2RS bearing are typically made from high-carbon chromium bearing steel (GCr15). This material undergoes precise heat treatment to achieve a hardness of 60-65 HRC, ensuring excellent wear resistance and fatigue strength. It allows the bearing to handle both radial and axial loads effectively, even during prolonged use.

2. Ball Material: The rolling balls are also crafted from chrome steel. Their high dimensional precision and smooth surface finish reduce friction between the balls and the rings, contributing to the bearing's efficient operation and long service life.

3. Cage Material: The cage, which keeps the balls evenly spaced, is usually made of low-carbon steel. This material offers sufficient strength to withstand the forces generated during rotation while maintaining the proper alignment of the balls, ensuring stable performance.

4. Seal Material: The double-sided seals are made of nitrile rubber (NBR). This rubber type has good resistance to oils, greases, and most industrial fluids, forming an effective barrier against dust, moisture, and other contaminants. The seals are bonded to a metal reinforcement, ensuring secure attachment to the bearing rings.

Characteristics

1. Effective Sealing: The nitrile rubber seals of the 682 2RS bearing provide a tight seal, preventing the ingress of dust, dirt, and moisture into the bearing interior. This protection helps maintain the integrity of the lubricant, reducing wear and extending the bearing's service life, making it suitable for use in relatively harsh environments.

2. Compact Size: With a bore diameter of 2mm, an outer diameter of 5mm, and a width of 2.3mm, the 682 2RS is a miniature bearing. Its small dimensions allow it to be installed in tight spaces, such as in small electrical components, precision instruments, and micro-mechanical devices.

3. Low Friction Operation: The combination of high-quality materials, precision manufacturing, and proper lubrication results in low friction within the bearing. This low friction contributes to efficient power transmission, reduces heat generation, and enables smooth rotation, which is crucial for applications requiring precise movement.

4. Versatile Load Handling: As a deep groove ball bearing, the 682 2RS can handle both radial loads and moderate axial loads in both directions. This versatility makes it suitable for a wide range of applications where different types of loads are encountered.

5. Cost-Effective: Compared to some specialized bearings, the 682 2RS offers a good balance of performance and cost. Its reliable operation and relatively low production cost make it an economical choice for many industrial and consumer applications.

Applications

1. Small Electrical Motors: The 682 2RS bearing is commonly used in small motors, such as those in toys, small fans, and electric shavers. Its compact size, low friction, and sealing properties ensure the motors run smoothly and efficiently, even in dusty or slightly humid environments.

2. Precision Instruments: In devices like watches, cameras, and measuring tools, the 682 2RS plays a vital role. Its small size and precise operation help maintain the accuracy and reliability of these instruments, where even minor deviations can affect performance.

3. Medical Devices: Some small medical devices, such as insulin pumps and portable diagnostic equipment, utilize the 682 2RS bearing. The bearing's sealing capability ensures it operates cleanly and reliably in medical settings, where hygiene and precision are of utmost importance.

4. Office Equipment: Components in printers, scanners, and small office appliances often incorporate the 682 2RS bearing. Its smooth rotation and compact design contribute to the efficient operation of these devices, reducing noise and ensuring consistent performance.

5. Automotive Accessories: Small automotive accessories like windshield wipers' micro-motors and interior fans may use the 682 2RS bearing. Its ability to withstand the vibration and occasional exposure to moisture in automotive environments makes it a suitable choice.
