SF683zz Bearing Product Overview & Core Advantages
The SF683zz is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing with shielded construction, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its small footprint (3mm bore, 7mm OD) combined with a flanged design provides secure mounting and positioning, ideal for applications where space is limited and high reliability is critical.
SF683zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| zz | Double-sided metal shields (non-contact) | Provides effective protection against contamination while maintaining high-speed capability. |
| Flanged | Outer ring features an integral flange (8.1mm diameter) | Simplifies axial location and mounting, enhancing assembly precision. |
SF683zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 3×7×3mm and weighing only 0.53g, this bearing is ideal for space-constrained miniature applications.
- Stainless Steel Construction: All components (rings, balls, cage, shields) are made from stainless steel, providing excellent corrosion resistance and durability.
- Shielded Protection: The double-sided metal shields retain lubricant and exclude contaminants, extending service life without significant speed penalty.
- Precision Performance: Manufactured to ABEC1 tolerance class with MC3 clearance (0.002-0.013mm), ensuring smooth operation and consistent performance.
- High-Speed Capability: The optimized design supports limiting speeds up to 56,700 rpm, suitable for demanding rotational applications.
- Flanged Outer Ring: Provides positive location and simplifies installation in housings, improving overall system reliability.
