F681xzz Bearing Product Overview & Core Advantages
The F681xzz is a miniature shielded ball bearing designed for ultra-compact applications requiring reliable performance in limited spaces. As a single row deep groove ball bearing, it excels at handling radial loads while offering smooth operation. Its primary advantages include a compact flange design for secure mounting, a shielded construction for contaminant protection, and compliance with ABEC1 precision standards, making it ideal for high-reliability miniature mechanisms.
F681xzz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| F681 | Basic bearing designation indicating bore diameter (1.5mm), outside diameter (4mm), and series | Defines core bearing dimensions and series classification |
| x | (Placeholder for specific flange/design variations) | Indicates potential design modifications |
| zz | Double-sided shielded (non-contact) construction | Provides effective contaminant exclusion while maintaining high-speed capability |
F681xzz Bearing Structural Features & Performance Benefits
- Flange Design: The integrated flange (OD: 5mm) enables simplified mounting and precise axial positioning, reducing assembly complexity in compact spaces.
- Shielded Protection: Double-sided 300 series stainless steel shields protect against particulate contamination while minimizing friction for high-speed operation up to 100,000 rpm.
- Precision Construction: Manufactured to ABEC1 tolerance class with MC3 radial clearance (0.002-0.013mm) ensures consistent performance and smooth rotation.
- Material Excellence: Chrome steel rings and balls combined with stainless steel cage provide corrosion resistance and durability in demanding miniature applications.
