7307 BECBM Bearing Product Overview & Core Advantages
The 7307 BECBM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This precision bearing is designed to accommodate high radial loads and axial loads in one direction simultaneously, making it ideal for demanding, high-speed machinery. Its P6 (ABEC-3) tolerance class ensures superior running accuracy, while the brass cage and optimized internal geometry contribute to its high rigidity and stable operation at the limiting speed of 14,000 rpm.
7307 BECBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| BE | High Capacity & Optimized Internal Design | Increased dynamic load rating for longer service life. |
| C | 15° Nominal Contact Angle | Excellent capability for handling axial loads. |
| BM | Brass (Copper Alloy) Cage | Provides high strength, excellent guidance, and suitability for high-speed operation. |
7307 BECBM Bearing Structural Features & Performance Benefits
The performance of the 7307 BECBM is derived from its specific construction. The 40° contact angle is a key feature, providing a superior balance between radial and axial load carrying capacity. The one-piece, machined brass cage (BM) ensures precise ball guidance and stability, which is critical for achieving the high limiting speed. The open design allows for optimal lubrication flow and heat dissipation. With a radial dynamic load rating of 9338 lbf and a static load rating of 5962 lbf, this bearing offers reliable performance in rigorous applications. The bearing dimensions (35mm bore, 80mm OD, 21mm width) are manufactured to strict P6 tolerance for consistent, high-precision fit and function.
