679zz Bearing Product Overview & Core Advantages
The 679zz is a metric single row deep groove ball bearing engineered for reliable performance in compact, high-speed applications. Featuring shielded construction, it offers effective protection against contamination while maintaining low friction. This bearing is designed to primarily handle radial loads and is characterized by its small cross-section, low weight, and smooth operation. Manufactured to ABEC1 precision tolerances, it provides consistent performance essential for applications demanding high rotational accuracy and reliability.
679zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 679 | Bearing series designation indicating specific dimensions: 9mm bore, 14mm OD, 4.5mm width. |
| zz | Dual shields (non-contact) on both sides, providing effective contamination protection while allowing high-speed operation. |
679zz Bearing Structural Features & Performance Benefits
Optimized Deep Groove Design: The raceway geometry enables efficient handling of radial loads and moderate axial loads in both directions, ensuring stable operation.
High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and non-contact shields enables a limiting speed of 36,000 rpm, making it suitable for demanding rotational applications.
Enhanced Contamination Resistance: The 300 series stainless steel shields protect the internal bearing components from dust and debris, extending service life and reducing maintenance needs.
Precision Engineering: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), this bearing delivers consistent performance, low vibration, and smooth running characteristics.
679zz Bearing Typical Application Areas
The 679zz bearing is widely used in applications requiring compact size, high speed, and reliable performance:
- Small Electric Motors: Spindle motors, drone motors, and precision DC motors
- Office Equipment: Printers, scanners, and copiers
- Medical Devices: Dental handpieces, small pumps, and laboratory equipment
