Material

1. Ring Material: The inner and outer rings are manufactured from high-carbon chromium bearing steel (GCr15), a material renowned for its exceptional hardness (60-65 HRC after heat treatment) and wear resistance. This steel composition ensures the rings can withstand both radial and axial loads while maintaining dimensional stability, even under prolonged use.

2. Ball Material: The rolling balls are also made from chrome steel, selected for their high roundness and smooth surface finish. These properties minimize friction between the balls and the raceways, reducing energy loss and extending the bearing's service life.

3. Cage Material: The cage, which maintains uniform spacing between the balls, is typically constructed from low-carbon steel. This material offers sufficient strength to resist centrifugal forces during rotation, ensuring the balls remain properly aligned for consistent performance.

4. Seal Material: The double-sided seals are composed of nitrile rubber (NBR), a material chosen for its excellent resistance to oils, greases, and moderate temperatures (up to 100°C). The rubber is bonded to a metal backing, allowing secure attachment to the outer ring while creating a tight seal that prevents dust, moisture, and contaminants from entering the bearing interior.

Characteristics

1. Effective Sealing Performance: The NBR rubber seals form a reliable barrier against liquids, dust, and debris, making the MR62 2RS ideal for use in damp or dirty environments. This sealing capability protects the bearing's lubricant, reducing the risk of premature wear and ensuring long-term reliability.

2. Compact Design: With a bore diameter of 2mm, outer diameter of 6mm, and width of 2.5mm, the MR62 2RS is designed for space-constrained applications. Its small footprint allows integration into miniature devices where every millimeter of space matters.

3. Low Friction Operation: The precision-machined components, combined with the smooth interaction between the chrome steel balls and raceways, result in low friction. This translates to efficient power transmission, reduced heat generation, and quiet operation—critical features for sensitive equipment.

4. Versatile Load Handling: As a deep groove ball bearing, it efficiently handles both radial loads and light to moderate axial loads in both directions. This versatility enables its use in applications with varying load requirements.

5. Cost-Effective Reliability: The MR62 2RS offers a balance of performance and affordability, providing reliable sealing and operation without the high cost of specialized bearings. Its durable construction also reduces maintenance needs, making it an economical choice for mass-produced devices.

Applications

1. Medical Devices: In small medical equipment such as insulin pumps, portable nebulizers, and diagnostic tools, the MR62 2RS excels. Its sealing performance protects against bodily fluids and dust, while its compact size fits seamlessly into handheld or wearable devices.

2. Consumer Electronics: It is widely used in components like small DC motors in smartphones (vibration motors), camera lens actuators, and portable audio devices. The low noise and smooth operation ensure a high user experience, while the seals protect against dust and moisture in daily use.

3. Precision Instruments: Devices such as digital calipers, laser levels, and optical sensors rely on the MR62 2RS for precise rotational movement. Its compact size and low friction contribute to the accuracy of these instruments, where even minor deviations can affect measurements.

4. Hobby and Toy Motors: Miniature motors in remote-controlled toys, model airplanes, and robotics kits often use this bearing. The sealing feature protects against dirt from outdoor use, while its smooth operation ensures consistent motor performance.

5. Industrial Micro-Mechanisms: In small conveyor systems, textile machinery components, and automated dispensers, the MR62 2RS provides reliable rotation. Its ability to handle light loads and resist contaminants makes it suitable for continuous operation in industrial settings.
