627-2RSH/W64 Bearing Product Overview & Core Advantages
The 627-2RSH/W64 is a metric single row deep groove ball bearing engineered for superior performance in compact spaces. This sealed bearing is designed primarily for radial loads and offers exceptional reliability. Its key advantages include maintenance-free operation due to integrated solid lubrication, consistent performance across a wide temperature range, and compliance with major industry standards like ROHS and REACH, making it an ideal choice for applications demanding high reliability and long service life.
627-2RSH/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 627 | Basic bearing series, indicating a metric, single row deep groove design. |
| 2RSH | Sealed on both sides with high-performance, high-temperature resistant contact seals. This provides excellent protection against contamination. |
| W64 | Indicates the bearing is pre-lubricated with Solid Oil, a polymer matrix saturated with oil. This offers a maintenance-free, long-lasting lubrication solution. |
627-2RSH/W64 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength and durability. It features a CN radial internal clearance and a dynamic load rating of 629 lbf, providing reliable performance under significant radial stresses.
- Maintenance-Free & Contamination Resistant: The combination of 2RSH contact seals and Solid Oil (W64) lubrication creates a sealed, self-lubricating system. This eliminates the need for re-lubrication and effectively shields the bearing from dust, moisture, and other contaminants, significantly extending its operational life.
- Precision & Stable Operation: Built to ABEC 1 | ISO P0 tolerance class, the bearing guarantees consistent running accuracy and smooth operation, which is critical for reducing vibration and noise in precision applications.
- Wide Operating Range: The Solid Oil lubrication enables a broad operating temperature range from -30°C to 120°C, making it suitable for various environmental conditions.
627-2RSH/W64 Bearing Typical Application Areas
This versatile and reliable bearing is ideally suited for a wide range of compact machinery and devices, including:
- Small electric motors and gear motors
- Precision instruments and medical devices
- Office automation equipment (e.g., printers, scanners)
- Food processing machinery (benefiting from its sealed, maintenance-free design)
- Ventilation fans and blowers
- Various light-duty industrial drives and conveyors
