7307 BEGBP Bearing Product Overview & Core Advantages
The 7307 BEGBP is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional performance. As a single row bearing with a 40° contact angle, it is specifically designed to support high combined loads, accommodating significant axial loads in one direction alongside radial loads. Manufactured to P6 (ABEC-3) tolerance class, it ensures high running accuracy and system rigidity. Its optimized internal geometry and Nylon cage contribute to superior high-speed performance, making it an ideal choice for precision machinery where reliability and accuracy are paramount.
7307 BEGBP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 7307 | Basic Bearing Number | Indicates a metric series bearing with a 35mm bore, 80mm OD, and 21mm width. |
| BE | High Capacity & Optimized Internal Design | Signifies an enhanced internal design with a larger ball complement and optimized raceway geometry for increased load capacity. |
| GB | 40° Contact Angle | Denotes a steep contact angle, providing high axial load carrying capability and system rigidity. |
| P | Glass Fiber Reinforced Nylon Cage | Specifies a lightweight, robust cage material ideal for high-speed operation, offering low friction and excellent acceleration characteristics. |
7307 BEGBP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 40° contact angle and BE-design with more and larger balls significantly increase the bearing's ability to handle heavy combined loads, providing stable and rigid support for shafts.
- Superior High-Speed Performance: The lightweight Nylon cage (P) minimizes centrifugal forces, reduces friction, and allows for a high limiting speed of 11,000 rpm, making it suitable for demanding high-speed applications.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing ensures minimal runout and high dimensional stability, which is critical for the accuracy of precision spindles and machinery.
- Optimized Lubrication: The bearing is supplied lubricated, ready for immediate use, and operates effectively within a temperature range of -30°C to 110°C.
7307 BEGBP Bearing Typical Application Areas
