7308 BEGAP Bearing Product Overview & Core Advantages
The 7308 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This metric bearing is characterized by its ability to support significant radial loads and unidirectional axial loads simultaneously, thanks to its specific 40° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and is pre-lubricated for immediate use. Its compact design, featuring a 40 mm bore, 90 mm outside diameter, and 23 mm width, makes it an ideal choice for applications demanding high rigidity and reliable operation in demanding environments.
7308 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Designates an increased contact angle (40° in this case) for handling higher axial loads. |
| GA | Indicates the bearing is supplied with a standard preload for enhanced stiffness and precise shaft positioning. |
| P | Specifies the P6 tolerance class, equivalent to ABEC-3, ensuring high precision and minimal runout. |
7308 BEGAP Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to support combined radial and axial loads effectively. The GA preload further increases system rigidity, minimizing deflection under load.
- Precision Performance: Manufactured to P6 tolerance, this bearing guarantees high running accuracy, making it suitable for precision machinery. The optimized bearing dimensions and internal geometry contribute to smooth and precise rotation.
- High-Speed Capability: The lightweight nylon cage reduces centrifugal forces, enabling a high limiting speed of 10,000 rpm, which is ideal for high-speed applications.
- Ready-to-Use and Durable: The bearing is pre-lubricated and features an open seal type, allowing for optimal re-lubrication in service. Constructed from chrome steel for both rings and balls, it offers excellent durability and a long service life.
7308 BEGAP Bearing Typical Application Areas
The 7308 BEGAP is ideally suited for high-performance applications across various industries, including:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Robotics and Automation
