626zz Bearing Product Overview & Core Advantages
The 626zz is a metric single row deep groove ball bearing designed for high performance in compact spaces. Engineered for primarily radial loads, it features integral shielded protection for enhanced contamination resistance. Manufactured to ABEC1 precision tolerances, this bearing offers reliable operation and is a fundamental component for applications demanding high rotational speeds and consistent performance. Its compact dimensions (6mm bore, 19mm OD) make it an ideal choice for space-constrained designs.
626zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| zz | Signifies that the bearing is equipped with shields on both sides. These non-contact shields protect the internal components from large particulate contaminants while minimizing friction, contributing to the high limiting speed. |
626zz Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and six chrome steel balls enable the bearing to efficiently handle significant radial dynamic loads (447 lbf) and moderate axial loads in both directions.
- High-Speed Capability: The combination of a stainless steel cage for precise ball guidance, low-friction shields, and a balanced internal design allows for a high limiting speed of 32,000 rpm.
- Precision & Rigidity: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring smooth, quiet, and vibration-free operation for enhanced application performance.
- Durability & Corrosion Resistance: Components made from chrome steel and a 300 series stainless steel shield provide excellent wear resistance and protection against corrosion in demanding environments.
626zz Bearing Typical Application Areas
This versatile bearing is widely used in:
- Small Electric Motors (e.g., in power tools, cooling fans, drones)
- Precision Instruments and optical devices
- Office Automation Equipment (printers, scanners, copiers)
- Computer Peripherals (hard disk drives, spindle motors)
- Light-duty gearboxes and mechanical drives
