F682 Bearing Product Overview & Core Advantages
The F682 is a miniature metric ball bearing designed for applications demanding compact size and reliable performance. As a single row deep groove ball bearing with an open design, it excels in handling radial loads efficiently. Its construction from high-grade chrome steel ensures durability, while its extremely small dimensions (2mm bore, 5mm OD) make it ideal for precision instruments and compact mechanisms requiring a high limiting speed of 85,000 rpm.
F682 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F682 | Standard model number for a miniature deep groove ball bearing with a 2mm bore, 5mm outside diameter, and 1.5mm width. |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication, but requiring a clean operating environment. |
| ABEC1 | Specifies the tolerance class, indicating standard precision levels for runout and dimensions. |
| MC3 | Denotes the radial internal clearance group, which is greater than normal (CN), suitable for applications with potential thermal expansion. |
F682 Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: The deep groove geometry enables the bearing to handle both radial and light axial loads, while the single-row construction maintains a minimal cross-section, crucial for miniature bearing applications.
- High-Speed Capability: The combination of an open design, a lightweight stainless steel cage, and six precision balls allows the F682 to achieve a limiting speed of 85,000 rpm, making it a true high-speed bearing in its size class.
- Precision Engineering: Manufactured to ABEC1 tolerances, this bearing provides consistent and reliable performance, with controlled dimensional accuracy for smooth operation.
- Material Integrity: Rings and balls made from chrome steel provide excellent wear resistance and fatigue life, while the stainless steel cage offers corrosion resistance and strength.
F682 Bearing Typical Application Areas
The F682 miniature ball bearing is engineered for use in a wide range of small-scale, high-precision equipment, including:
- Small DC Motors and Stepper Motors
- Precision Instruments and Optical Encoders
- Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., small printers, scanners)
- Radio-Control Models and Drones
- Small Fans and Pumps
