7308 BEGAM Bearing Product Overview & Core Advantages
The 7308 BEGAM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. Its defining characteristic is the 40° contact angle, which provides superior axial load capacity in one direction while handling significant radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures high running accuracy and is pre-lubricated for immediate operation. Its compact design and robust construction make it an ideal solution for high-speed, high-rigidity applications demanding reliability and long service life.
7308 BEGAM Bearing Model Code Explained, Specifications & Naming Convention
The model number 7308 BEGAM can be broken down as follows:
- 7308: Basic designation indicating a metric, single row angular contact ball bearing with a 40mm bore.
- B: Denotes a 40° contact angle, optimized for high axial load capacity.
- E: Signifies an optimized internal design, including a larger ball complement and reinforced raceway, for increased load rating.
- GAM: Indicates the bearing is supplied with a premium lubricant suitable for the specified temperature range and high-speed operation.
7308 BEGAM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is specifically engineered to support high combined (radial and axial) loads. The reinforced internal geometry (E-design) significantly increases both the dynamic and static load ratings.
- High-Speed Performance: The brass cage ensures dimensional stability and low friction at high rotational speeds, contributing to a high limiting speed. The optimized internal geometry minimizes heat generation.
- Precision and Accuracy: Manufactured to P6 tolerance, this bearing guarantees precise shaft guidance and low runout, which is critical for applications like machine tool spindles.
- Ready-to-Use: The bearing is pre-lubricated, simplifying installation and ensuring immediate, reliable performance right out of the box.
7308 BEGAM Bearing Typical Application Areas
The 7308 BEGAM is ideally suited for demanding applications across various industries, including:
- Machine Tool Spindles: High-speed machining centers and lathes.
- Pumps and Compressors: For handling significant axial thrust loads.
- Gearboxes and Power Transmission Systems.
- Precision Industrial Machinery requiring high rigidity and accuracy.
