7209 ACCBM Bearing Product Overview & Core Advantages
The 7209 ACCBM is a single row angular contact ball bearing designed for applications requiring high precision and superior performance under combined loads. Engineered with a 25° contact angle and manufactured to P6 (ABEC-3) tolerance class, this bearing excels at simultaneously handling significant radial loads and unidirectional axial loads. Its open design facilitates optimal lubrication management, contributing to its high limiting speed of 15,000 rpm. Constructed from high-grade chrome steel with a durable brass cage, it offers exceptional reliability for demanding industrial environments.
7209 ACCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7209 | Standard bearing series designation indicating a 45mm bore, 85mm OD, and 19mm width. |
| AC | Angular Contact design, optimized for combined radial and axial loads. |
| C | Specifies a 25° contact angle, providing a balanced capacity for axial and radial loads. |
| BM | Indicates the bearing is Lubricated for immediate operation. |
7209 ACCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, combined with a 25° contact angle and robust chrome steel construction, provides high rigidity. This enables the bearing to support substantial combined loads (radial dynamic load rating: 9900 lbf, static: 7200 lbf) effectively.
- High-Speed Performance: The precision brass cage ensures stable operation and guides the balls efficiently, which is critical for achieving the high limiting speed of 15,000 rpm.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional control on the bore diameter (45 mm) and outside diameter (85 mm), ensuring predictable performance and ease of integration into precision assemblies.
- Optimized Internal Geometry: Features like the specified shoulder diameters (outer ring: 70.05 mm) and chamfer dimension (1.1 mm) are designed for precise locating and secure mounting.
