209SZZCG Bearing Product Overview & Core Advantages
The 209SZZCG is a single row deep groove ball bearing designed for radial load applications requiring reliable performance. Featuring shielded construction on both sides, this metric bearing offers excellent contamination protection while maintaining smooth operation. Manufactured with chrome steel components throughout (rings, balls, and cage), it delivers consistent durability and long service life. With its ABEC 1 precision class and standardized CN radial clearance, it provides dependable performance for general industrial applications across a wide temperature range (-30° to 120°C).
Model Code Detailed Breakdown

| 209 | Standard bore diameter code (45mm) | Indicates standard dimension series for compatibility |
| S | Single row design | Compact construction for space-constrained applications |
| ZZ | Double shielded (both sides) | Enhanced contamination protection for extended bearing life |
| CG | Chrome steel cage material | Improved strength and temperature resistance |
209SZZCG Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables efficient radial load distribution while accommodating moderate axial loads in both directions, making it versatile for various mounting configurations.
Double Shielded Protection: Both sides feature non-contact steel shields that effectively prevent the ingress of contaminants while minimizing friction, contributing to the 8,500 rpm limiting speed capability.
Full Chrome Steel Construction: The integration of chrome steel for rings, balls, and cage ensures uniform thermal expansion characteristics and consistent performance across the specified temperature range, while providing excellent wear resistance.
Precision Engineering: Manufactured to ABEC 1 (ISO P0) tolerance class with CN radial internal clearance, this bearing delivers reliable operation with minimal vibration for general precision applications.
