625-2Z Bearing Product Overview & Core Advantages
The 625-2Z is a metric single row deep groove ball bearing designed for superior performance in compact spaces. This shielded bearing excels in applications requiring reliable radial load support and high-speed operation. Its P6 tolerance class ensures high running accuracy, making it ideal for precision mechanisms. The pre-lubricated grease and integrated shields provide long-term, maintenance-free operation, enhancing equipment reliability and reducing total cost of ownership.
625-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 625 | Basic bearing series designation, indicating a metric deep groove ball bearing with a 5mm bore and 16mm OD. | Standardized dimensions for easy interchangeability and sourcing. |
| -2Z | Bearing is equipped with non-contact shields on both sides. | Effective contamination protection without significantly increasing friction, preserving the high limiting speed of 48,000 rpm. |
625-2Z Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry & High-Grade Materials: The deep groove raceway and chrome steel rings and balls are engineered for smooth operation and long service life under radial dynamic loads up to 256 lbf.
- Superior Cage Design: The stainless steel cage provides excellent guidance and stability at high speeds, contributing to the bearing's reliable performance up to its limiting speed.
- Sealed & Pre-Lubricated for Longevity: The combination of ZZ shields and factory-applied grease creates a sealed, lubricated environment. This design effectively excludes contaminants and retains lubrication, enabling maintenance-free operation across a wide temperature range of -30°C to 120°C.
- Precision Performance: Manufactured to P6 tolerance and standard CN radial internal clearance, this bearing ensures high running accuracy and minimal vibration, which is critical for sensitive applications.
625-2Z Bearing Typical Application Areas
The 625-2Z is a versatile component found in a wide array of precision equipment and small machinery, including:
- Small Electric Motors (e.g., for drones, power tools, cooling fans)
- Precision Instruments and optical devices
- Office machinery such as printers and scanners
- Medical and dental handpieces
- Radio-controlled models and small gearboxes
