697zz Bearing Product Overview & Core Advantages
The 697zz is a single row deep groove ball bearing designed for high-performance radial load applications. Engineered with precision ABEC1 tolerances and shielded construction, it offers reliable operation and protection from contamination. Its compact design, featuring a 7 mm bore and 17 mm outside diameter, makes it ideal for applications demanding space efficiency without compromising on load capacity or durability. The use of high-grade chrome steel for rings and balls ensures excellent wear resistance and a long service life.
697zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 697 | Standard bearing series designation, indicating a metric, single row deep groove ball bearing with a 7mm bore, 17mm OD, and 5mm width. |
| zz | Denotes shielded construction on both sides. The shields (made from 300 Series Stainless Steel) protect the internal components from dust and debris while minimizing friction. |
697zz Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The deep groove raceway and 9 high-precision chrome steel balls are engineered to efficiently support significant radial dynamic loads (307 lbf) and radial static loads (129 lbf).
- Shielded for Protection & Longevity: The non-contact stainless steel shields retain lubricant and exclude contaminants, enhancing bearing life and reliability in challenging environments. This design contributes to a limiting speed of 36,000 rpm.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.002mm to 0.013mm), ensuring smooth and consistent operation with minimal vibration.
- Robust Cage Design: The stainless steel cage precisely spaces and guides the balls, providing stability at high speeds and contributing to the bearing's overall durability.
697zz Bearing Typical Application Areas
- Small Electric Motors (e.g., in power tools, drones, cooling fans)
- Precision Instruments and Optical Devices
- Office Machinery (printers, scanners)
- Radio-Controlled Models and Hobbyist Projects
- Light-Duty Industrial Gearboxes and Spindles
