S697zz Bearing Product Overview & Core Advantages
The 697zz is a single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features a stainless steel construction and integrated shielded design, offering excellent protection against contamination. Its compact dimensions (7mm bore, 17mm OD, 5mm width) make it ideal for applications with space constraints. Engineered for primarily radial loads, it delivers smooth operation and long service life, making it a robust and cost-effective solution for a wide range of industrial and precision equipment.
S697zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 697 | Bearing Series & Size Code | Denotes a specific series of miniature deep groove ball bearings with a 7mm bore, 17mm outside diameter, and 5mm width. |
| zz | Shield Configuration | Indicates the bearing is equipped with non-contact shields (Z-shields) on both sides. This provides effective protection against dust and debris while minimizing friction and allowing for higher limiting speeds compared to contact seals. |
S697zz Bearing Structural Features & Performance Benefits
Stainless Steel Construction: Manufactured from 300 series stainless steel for the rings, balls, cage, and shields, this bearing offers excellent corrosion resistance, making it suitable for applications exposed to moisture or harsh environments.
Deep Groove Raceway: The deep, continuous raceways on both rings are optimized to support significant radial dynamic load ratings (276 lbf) and moderate axial loads in both directions.
Shielded Design: The ZZ shields retain lubricant and effectively exclude contaminants, enhancing bearing life and reliability without the added friction of contact seals. This contributes to its high limiting speed of 32,400 rpm.
Precision & Clearance: Built to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent performance, smooth running, and low noise operation.
S697zz Bearing Typical Application Areas
The 697zz bearing is widely used in applications requiring compact size, corrosion resistance, and reliable operation. Key industries and equipment include:
- Small Electric Motors (e.g., cooling fans, drone motors)
- Precision Instruments and Optical Devices
- Office Automation Equipment (printers, scanners)
- Medical Devices and Laboratory Equipment
- Radio Control Models and Hobbyist Projects
- Food Processing Machinery (where corrosion resistance is critical)
