627-2Z Bearing Product Overview & Core Advantages
The 627-2Z is a metric single row deep groove ball bearing engineered for high performance and reliability in compact spaces. Its shielded design (2Z) provides effective contamination protection while the P6 tolerance class ensures precise operation. This bearing excels in applications requiring robust radial load capacity and consistent performance, making it an ideal choice for high-speed machinery and precision instruments where space constraints and operational reliability are critical.
Model Code Breakdown
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 627 | Basic bearing series | Indicates standard deep groove design with 7mm bore, 22mm OD |
| 2Z | Double shielded both sides | Provides superior protection against contaminants while maintaining high-speed capability |
627-2Z Bearing Structural Features & Performance Benefits
Optimized Load Handling: The single row deep groove construction delivers excellent radial load capacity (776 lbf dynamic, 308 lbf static) while accommodating moderate axial loads in both directions.
High-Speed Performance: Featuring a stainless steel cage and factory-applied grease lubrication, this bearing achieves a limiting speed of 36,000 rpm, making it suitable for demanding high-speed applications.
Precision Engineering: Manufactured to P6 tolerance class with CN radial clearance, ensuring consistent performance and minimal vibration in precision applications.
Extended Service Life: The combination of chrome steel rings and balls with double shielding provides corrosion resistance and contamination protection, reducing maintenance requirements.
627-2Z Bearing Typical Application Areas
- Small Electric Motors: Ideal for spindle motors, drone motors, and precision servo motors requiring high-speed operation
- Office Automation Equipment: Printers, scanners, and copiers where reliable, quiet operation is essential
- Medical Devices: Dental handpieces, laboratory equipment, and small medical instruments
- Precision Instruments: Optical encoders, measuring devices, and scientific instruments
