628-2Z Bearing Product Overview & Core Advantages
The 628-2Z is a metric single row deep groove ball bearing designed for high-performance applications requiring reliable operation and minimal maintenance. This shielded bearing excels in handling significant radial loads while offering protection from contaminant ingress. Its compact design, precision P6 tolerance, and pre-lubrication make it an ideal choice for applications demanding high rotational accuracy and long service life without re-lubrication.
628-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 628 | Basic bearing series, indicating a metric deep groove ball bearing with 8 mm bore, 24 mm OD, and 8 mm width. |
| 2Z | Non-contact shields on both sides, providing effective protection against dust and other contaminants while minimizing friction and heat generation. |
628-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P6 tolerance class with a CN radial internal clearance, ensuring smooth operation, precise shaft positioning, and excellent running accuracy for demanding applications.
- Robust Load Capacity: The deep groove raceway and chrome steel construction enable a high dynamic load rating of 877 lbf and a static load rating of 373 lbf, providing reliable performance under substantial radial loads.
- Optimized High-Speed Performance: The stainless steel cage and optimized grease lubrication contribute to a high limiting speed of 32,000 rpm, making it suitable for high-velocity applications.
- Maintenance-Free Operation: The combination of non-contact shields (2Z) and factory-applied grease seals in the lubricant and protects the bearing interior, enabling long-term, maintenance-free operation within a temperature range of -30°C to 120°C.
628-2Z Bearing Typical Application Areas
- Electric Motors and small precision gearboxes
- Office Automation Equipment such as printers, scanners, and copiers
- Medical Devices and laboratory instrumentation
- Small Fans, blowers, and pumps
- Textile Machinery spindles and guides
