209SG Bearing Product Overview & Core Advantages
The 209SG is a single row deep groove ball bearing engineered for high performance in demanding applications. As a metric bearing with an open design, it excels in handling significant radial loads while offering moderate axial load capacity. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides reliable and consistent operation. Its robust construction from chrome steel ensures durability, making it an ideal choice for applications requiring a balance of high load capacity and operational reliability.
209SG Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 209 | Standard bearing series designation, indicating the boundary dimensions (45mm bore, 85mm OD, 19mm width). |
| SG | Signifies the use of a Chrome Steel cage. This material offers excellent strength and is suitable for a wide temperature range. |
| No Seal Suffix | The open seal type allows for high-speed operation and facilitates relubrication or the use of different lubricants as required by the application. |
209SG Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove raceway and chrome steel construction enable a high radial dynamic load rating of 7913 lbf and a static load rating of 6744 lbf, providing robust performance under significant stress.
- Optimized for Speed: The open design and chrome steel cage (SG) contribute to a high limiting speed of 8,500 rpm, minimizing friction and heat generation.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, ensuring smooth and precise rotation for general industrial applications.
- Versatile Lubrication: The open seal type provides flexibility, allowing the bearing to be lubricated with grease or oil tailored to specific operational needs, including high-temperature environments up to 120°C.
