SF692zz Bearing Product Overview & Core Advantages
The SF692zz is a miniature stainless steel ball bearing designed for applications demanding high precision and corrosion resistance. As a single row deep groove ball bearing with shielded construction, it excels in handling radial loads efficiently. Its compact design, featuring a 2 mm bore and 3 mm width, makes it ideal for space-constrained, high-reliability mechanisms. Manufactured from 300 series stainless steel, it offers excellent durability and performance in various environmental conditions.
SF692zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| zz | Non-contact steel shields on both sides | Provides effective protection against contamination while maintaining a low torque, suitable for high-speed operation. |
Note: The "SF692" base designation indicates a specific series of miniature flanged bearings with standard dimensions and internal construction.
SF692zz Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Built to ABEC1 tolerance class with a stainless steel cage, ensuring smooth operation and consistent performance under radial dynamic loads up to 57 lbf.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making it suitable for harsh environments and washdown applications.
- Optimized for High Speed: The non-contact shielded design and precision construction contribute to a high limiting speed of 67,500 rpm.
- Compact & Lightweight: With a total weight of only 0.45 g and a compact flange design (7.5 mm outer diameter), it enables efficient design in miniature assemblies.
- Standard Internal Clearance: Features an MC3 radial internal clearance (0.002mm to 0.013mm), suitable for a wide range of operating conditions and providing stable performance.
