7306 BEGAPH Bearing Product Overview & Core Advantages
The 7306 BEGAPH is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its design is optimized to simultaneously support significant radial loads and one-directional axial loads, making it an ideal solution for compact, high-rigidity arrangements. Manufactured to a P6 (ABEC-3) tolerance class, it guarantees exceptional running accuracy and operational reliability. The bearing comes pre-lubricated and features a lightweight nylon cage, contributing to its high limiting speed of 13,000 rpm and smooth operation.
7306 BEGAPH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7306 | Standard bearing series designation, indicating a 30 mm bore, 72 mm OD, and 19 mm width. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| P | Indicates the P6 tolerance class (equivalent to ABEC-3), ensuring high precision. |
| A | Signifies an open (unsealed) bearing design for direct lubrication access. |
| H | Denotes that the bearing is pre-lubricated with a high-performance grease. |
7306 BEGAPH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row angular contact design, with a generous 40° contact angle and optimized raceway geometry, provides high rigidity and enables the bearing to handle substantial combined radial and axial loads in one direction.
- High-Speed Performance: The lightweight and robust nylon cage minimizes centrifugal forces, reduces friction, and ensures stable operation at the high limiting speed of 13,000 rpm.
- Precision Engineering: Manufactured to P6 tolerance with tight dimensional control on the bore diameter, outside diameter, and width, this bearing delivers exceptional running accuracy and minimizes vibration.
- Material & Compliance: Constructed from high-grade chrome steel for both rings and balls, ensuring durability and long service life. The bearing is ROHS and REACH compliant.
