F682xzz Bearing Product Overview & Core Advantages
The F682xzz is a miniature metric single row deep groove ball bearing designed for applications requiring compact dimensions and reliable performance in high-speed operations. Featuring a shielded design and manufactured to ABEC1 precision tolerances, this bearing delivers stable radial load capacity and smooth rotation. Its stainless steel cage and shields provide excellent corrosion resistance, making it suitable for demanding environments where space is limited but performance is critical.
F682xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| F682 | Basic bearing series designation for miniature deep groove ball bearings |
| x | Placeholder for specific bore size variation (2.5mm in this configuration) |
| zz | Dual shielded construction providing effective contamination protection from both sides |
F682xzz Bearing Structural Features & Performance Benefits
Compact Design Excellence: With ultra-small bearing dimensions (2.5mm bore × 6mm OD × 2.6mm width) and a weight of only 0.42g, this bearing enables miniaturization in precision applications while maintaining structural integrity.
High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a limiting speed of 71,000 rpm, making it ideal for high-rotation applications.
Reliable Load Handling: Engineered with 8 chrome steel balls of 0.8mm diameter, the bearing provides a radial dynamic load rating of 40 lbf and static load rating of 13 lbf for consistent performance under radial loads.
Enhanced Protection: The 300 series stainless steel shields offer superior contamination protection while the MC3 radial internal clearance (0.002-0.013mm) ensures optimal performance across various operating conditions.
F682xzz Bearing Typical Application Areas
This miniature precision bearing is extensively used in:
- Small precision motors and micro-drives
- Medical devices and dental handpieces
- Optical encoders and precision instrumentation
- Miniature robotics and RC models
