626-2RSH/W64 Bearing Product Overview & Core Advantages
The 626-2RSH/W64 is a sealed single row deep groove ball bearing designed for exceptional performance in compact applications. This precision bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include maintenance-free operation due to integrated sealing and solid lubrication, high reliability, and suitability for high-speed applications. The combination of chrome steel components and ABEC 1 precision ensures consistent performance and long service life in demanding environments.
626-2RSH/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| 2RSH | Double Contact Seals (NBR Rubber) | Provides excellent contamination protection and retains lubrication effectively |
| W64 | Solid Oil Lubrication | Ensures maintenance-free operation, eliminates lubricant leakage, and offers consistent performance across the temperature range |
626-2RSH/W64 Bearing Structural Features & Performance Benefits
Optimized Sealing System: The 2RSH contact seals provide superior protection against contaminants while effectively retaining lubrication, significantly extending bearing service life in dirty environments.
Advanced Lubrication Technology: The W64 Solid Oil filling eliminates the need for relubrication, prevents oil leakage, and maintains stable lubrication performance across the entire operating temperature range (-30°C to 120°C).
High-Speed Capability: With a limiting speed of 32,000 rpm, this bearing is engineered for high-speed applications, supported by precision manufacturing and optimal internal clearance.
Radial Load Capacity: The deep groove raceway design enables efficient handling of radial dynamic loads up to 447 lbf, making it suitable for applications requiring reliable radial load support.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance standards with CN radial internal clearance, ensuring smooth operation and consistent performance in precision mechanisms.
