F679zz Bearing Product Overview & Core Advantages
The F679zz is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Featuring shielded construction on both sides, this bearing is designed to handle primarily radial loads while offering protection from contaminant ingress. Its small footprint, with a 9mm bore and 14mm outside diameter, makes it ideal for applications where space is at a premium. Manufactured to ABEC1 tolerance standards, it provides consistent performance and is pre-lubricated for immediate use, ensuring high reliability and long service life in demanding environments.
F679zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Indicates the bearing is equipped with shielded seals on both sides. These non-contact shields, made from 300 Series Stainless Steel, protect the internal components from dust and other contaminants while minimizing friction, contributing to the bearing's limiting speed of 36,000 rpm. |
F679zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and optimized shielded design allows for a high limiting speed, making it suitable for high-RPM applications.
- Robust Load Capacity: The deep groove raceway and construction with 12 precision balls enable efficient handling of radial dynamic loads up to 176 lbf and radial static loads up to 84 lbf.
- Precision & Consistency: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth operation, low noise, and minimal vibration.
- Durability & Corrosion Resistance: The use of stainless steel for the cage and shields enhances corrosion resistance, while the hardened chrome steel rings and balls provide excellent wear resistance for extended bearing life.
F679zz Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors (e.g., drones, RC models, small fans)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical Devices and Instrumentation
- Computer Peripheral Spindles (e.g., hard disk drives)
- Various light-duty industrial machinery requiring compact, reliable rotary support.
