209S Bearing Product Overview & Core Advantages
The 209S metric ball bearing is a high-performance single row deep groove ball bearing designed for reliable operation in a wide range of industrial applications. Engineered with precision tolerances (ABEC 1 / ISO P0), it offers exceptional running accuracy and stability. Its open design allows for versatile lubrication options, while its robust construction from chrome steel ensures high radial load capacity and long service life, making it an ideal choice for demanding environments.
209S Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 209S | Standard metric series deep groove ball bearing with specific dimension series. |
| Open (Seal Type) | No seals or shields, allowing for high-speed operation and custom lubrication regimes. |
| None (Lubrication) | Supplied without grease, providing flexibility for the user to apply a lubricant suitable for the specific application. |
209S Bearing Structural Features & Performance Benefits
- High Radial Load Capacity: The single row deep groove raceway and high-quality chrome steel construction enable it to handle significant radial dynamic loads up to 7913 lbf and static loads up to 6744 lbf.
- Optimized for Speed: The open design and standard CN radial internal clearance contribute to a high limiting speed of 8,500 rpm.
- Precision Engineering: Manufactured to ABEC 1 / ISO P0 tolerance class, ensuring smooth, quiet, and vibration-free operation, which is critical for precision machinery.
- Material Integrity: All core components—rings, balls, and cage—are made from chrome steel, providing excellent hardness, wear resistance, and durability.
- Broad Operating Range: Suitable for a temperature range from -30°C to 120°C, accommodating various operational environments.
