682x 2rs Bearing Product Overview & Core Advantages
The 682x 2rs is a metric miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. This sealed single row bearing excels in handling radial loads primarily, offering a robust solution for high-speed operations with a limiting speed of 71,000 rpm. Its sealed construction with nitrile rubber contact seals (2RS) provides effective contamination exclusion and grease retention, making it suitable for applications demanding low maintenance and long service life. Manufactured from chrome steel with an ABEC1 precision class, it delivers consistent performance and durability in constrained spaces.
682x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 68 | Series designation indicating a miniature deep groove ball bearing with a specific cross-section. |
| 2 | Bore size code. Corresponds to a 2.5 mm bore diameter in this series. |
| 2RS | Sealing type. Denotes two rubber contact seals, one on each side, providing superior protection against contaminants and grease leakage. |
682x 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The deep groove geometry on both inner and outer rings enables efficient handling of radial loads and moderate axial loads in both directions, offering versatile load capacity in a compact form.
- Sealed for Protection & Longevity: The inclusion of Nitrile Rubber (NBR) contact seals (2RS) effectively shields the internal components from dust, moisture, and other contaminants. This design retains lubrication, reduces friction, and significantly extends bearing service life, making it ideal for maintenance-free or difficult-to-access applications.
- High-Speed Capability: The combination of a stainless steel cage, precision ABEC1 tolerances, and optimized internal geometry allows for a high limiting speed of 71,000 rpm, suitable for demanding small motor and instrument applications.
- Precision Engineering: Built to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.002mm to 0.013mm), this bearing ensures smooth, low-vibration, and quiet operation, which is critical for sensitive electronic and precision mechanical systems.
682x 2rs Bearing Typical Application Areas
This miniature 682x 2rs bearing is ideally suited for a wide range of small-scale, high-precision mechanisms, including:
- Small Electric Motors (e.g., in drones, RC models, precision tools)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical and Dental Handpieces
- Precision Instruments and Gauges
- Computer Cooling Fans and small blowers
- Various miniature gearboxes and actuation systems
