7310 BECBM Bearing Product Overview & Core Advantages
The 7310 single row angular contact ball bearing is a precision bearing engineered for applications requiring high accuracy and reliable performance under combined loads. Its defining characteristic is the 40° contact angle, which enables it to support significant axial loads in one direction in addition to radial loads. Manufactured to a P6 (ABEC-3) tolerance class, it offers superior running accuracy, making it ideal for high-speed operations with a limiting speed of 10,000 rpm. The open design, combined with a robust brass cage, ensures optimal performance in demanding environments.
7310 BECBM Bearing Model Code Explained, Specifications & Naming Convention
| Code | Interpretation | Technical Significance |
|---|---|---|
| 7310 | Basic Bearing Number | Standard metric series bearing with a 50 mm bore, 110 mm OD, and 27 mm width. |
| - | Contact Angle Designation | Implies a standard 40° contact angle, optimized for axial load capacity. |
| (No Seal Suffix) | Open (Unsealed) | Allows for custom lubrication schemes and minimizes friction for high-speed performance. |
| P6 | Tolerance Class | Corresponds to ABEC-3, indicating high precision dimensional and running accuracy. |
7310 BECBM Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry: The 40° contact angle and precisely calculated shoulder diameters (73.8 mm inner ring large-side) are designed to effectively manage high axial loads from one direction while supporting radial loads.
- High-Speed Capability: The lightweight and durable brass cage maintains ball alignment and stability, contributing directly to the high limiting speed of 10,000 rpm.
- Robust Load Ratings: With a dynamic load rating of 16,875 lbf and a static load rating of 11,475 lbf, this bearing offers excellent load-carrying capacity and long service life.
- Precision Engineering: Manufactured to P6 tolerance with tight dimensional controls on bore, outside diameter, and width, ensuring consistent performance and ease of installation in precision machinery.
