7306 BEGBY Bearing Product Overview & Core Advantages
The 7306 BEGBY is a single row angular contact ball bearing designed for high-precision applications requiring superior performance under combined loads. Engineered to accommodate significant axial loads in one direction alongside radial loads, this bearing features a 40° contact angle for optimal thrust capacity. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and is pre-lubricated for immediate use. Its compact design, with a 30 mm bore and 72 mm outside diameter, makes it an ideal choice for high-speed spindles and other precision machinery demanding high rigidity and reliability.
7306 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| BE | Designates an increased contact angle of 40°, providing enhanced axial load carrying capacity. |
| GB | Indicates a brass cage, which offers excellent strength and guidance for high-speed operation and demanding conditions. |
| Y | Signifies that the bearing is pre-lubricated from the factory, ensuring immediate operation and simplifying installation. |
7306 BEGBY Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to handle high radial loads and substantial one-direction axial loads simultaneously, providing stable and rigid support for rotating shafts.
- High-Speed Performance: The robust brass cage (GB) ensures precise ball guidance and stability, contributing to the bearing's high limiting speed of 13,000 rpm.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees minimal running vibration and high positional accuracy, which is critical for precision applications.
- Ready-to-Use Lubrication: Being factory pre-lubricated (Y), the bearing offers immediate protection against wear and is suitable for the specified temperature range of -30°C to 110°C.
7306 BEGBY Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for applications requiring high precision and speed, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Agricultural Machinery
- Material Handling Equipment
