626/W64 Bearing Product Overview & Core Advantages
The 626/W64 is a metric single row deep groove ball bearing designed for exceptional performance in compact applications. This precision bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its open design and Solid Oil lubrication make it suitable for high-speed operation and applications requiring consistent performance across a wide temperature range. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable operation and long service life in demanding environments.
626/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 626 | Standard deep groove ball bearing series with 6mm bore, 19mm OD, and 6mm width. |
| W64 | Designates the bearing is pre-lubricated with Solid Oil, a polymer-based lubricant that provides long-term lubrication and is resistant to washout. |
626/W64 Bearing Structural Features & Performance Benefits
Optimized for High-Speed Operation: The open seal type minimizes friction, allowing the bearing to achieve a limiting speed of 32,000 rpm. The deep groove raceway and precision-ground components ensure smooth rotation and low vibration.
Solid Oil Lubrication Technology: The integrated Solid Oil filling offers significant advantages over traditional grease, including no leakage, excellent resistance to contamination and washout, and stable performance across a broad temperature range (-30°C to 120°C). This results in a maintenance-free design for the bearing's operational life.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, the bearing provides a dynamic load rating of 447 lbf and a static load rating of 161 lbf, ensuring durability under demanding radial load conditions.
Precision Engineering: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, this bearing guarantees consistent performance, low noise, and high running accuracy.
626/W64 Bearing Typical Application Areas
The 626/W64 is ideally suited for a wide range of compact, high-speed machinery and precision instruments, including:
- Small Electric Motors and spindles
- Office Automation Equipment (printers, scanners, copiers)
- Medical Devices and dental handpieces
- Precision Instruments and measuring devices
- Computer Cooling Fans and small gearboxes
