625-Z Bearing Product Overview & Core Advantages
The 625-Z is a metric single row deep groove ball bearing designed for high precision and reliable performance in compact spaces. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions. The inclusion of a shielded design (Z-type) and pre-lubrication ensures long service life with minimal maintenance, making it an ideal choice for applications demanding high rotational accuracy and consistent operation.
625-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 625 | Basic bearing series, indicating a metric, single row deep groove design with a 5 mm bore. |
| -Z | Denotes a non-contact shield on one side of the bearing. This provides effective protection against contamination while minimizing friction and torque. |
625-Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P6 tolerance class with a CN radial internal clearance, this bearing ensures smooth, precise rotation and stable operation under load.
- Robust Load Capacity: The optimized deep groove raceway and chrome steel construction provide a high dynamic load rating of 256 lbf, making it suitable for demanding radial load applications.
- Optimized for Speed: The stainless steel cage and effective grease lubrication contribute to a high limiting speed of 60,000 rpm, supporting high-speed operation.
- Enhanced Service Life: The combination of a shielded seal and factory-applied grease protects against contaminants and retains lubrication, resulting in a maintenance-free and long-lasting bearing solution.
625-Z Bearing Typical Application Areas
This versatile miniature bearing is commonly specified in:
- Small Electric Motors and Precision Gearboxes
- Medical and Dental Hand Tools
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Precision Measuring Devices
- Computer Cooling Fans and Small Appliances
