7307 BEGAM Bearing Product Overview & Core Advantages
The 7307 BEGAM is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rigidity and speed capability. Engineered to accommodate combined loads—simultaneously handling significant radial loads and unidirectional axial loads—this bearing is ideal for demanding machinery. Its P6 (ABEC-3) tolerance class ensures superior running accuracy, while the optimized 40° contact angle provides excellent axial load capacity. The combination of chrome steel rings, chrome steel balls, and a robust brass cage delivers reliable performance in high-speed and high-rigidity scenarios.
7307 BEGAM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7307 | Basic bearing designation indicating a metric single row angular contact ball bearing with 35mm bore, 80mm OD, and 21mm width. |
| BE | Designates increased contact angle (40°) and optimized internal geometry for enhanced axial load capacity. |
| GAM | Indicates the bearing is supplied lubricated with high-performance grease suitable for the specified temperature range. |
7307 BEGAM Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single row design with P6 tolerance and precisely ground raceways ensures minimal runout and stable operation under high loads, making it suitable for precision spindles.
- Superior Load Capacity: The 40° contact angle enables the bearing to efficiently support substantial combined radial and axial loads in one direction, a critical feature for applications like pump shafts and gearboxes.
- High-Speed Capability: The lightweight and durable brass cage (GAM designation) maintains ball guidance and stability, contributing to the high limiting speed of 14,000 rpm.
- Material & Durability: Components made from chrome steel provide high hardness and wear resistance, ensuring long service life under demanding operating conditions.
