7308 BEGAPH Bearing Product Overview & Core Advantages
The 7308 BEGAPH is a single row angular contact ball bearing engineered for precision applications requiring high rotational accuracy and reliable performance. This metric bearing features a 40 mm bore and is designed to accommodate combined loads, efficiently handling significant axial loads in one direction alongside radial loads. Its optimized 40° contact angle and P6 (ABEC-3) tolerance class ensure superior running accuracy, making it an ideal choice for high-speed spindles and other demanding machinery. The open design, complemented by a nylon cage, facilitates high limiting speeds and smooth operation.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7308 | Basic bearing designation indicating a metric, single row angular contact ball bearing with a 40 mm bore, 90 mm OD, and 23 mm width. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| P | Indicates the cage is made from glass fiber reinforced polyamide (nylon), offering low friction and suitability for high speeds. |
| A | Signifies the bearing is supplied with standard internal clearance. |
| PH | Denotes the bearing is pre-lubricated with grease, ready for immediate use. |
7308 BEGAPH Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The 40° contact angle is specifically engineered to support substantial one-direction axial loads, making it superior to standard deep groove ball bearings in thrust applications.
- High-Speed Performance: The lightweight nylon cage (P) minimizes centrifugal forces, reduces friction, and enables a high limiting speed of 10,000 rpm, which is critical for spindle and motor applications.
- Precision & Rigidity: Manufactured to P6 (ABEC-3) tolerance with strict dimensional control on the bore and outside diameter, this bearing provides high running accuracy and system rigidity.
- Optimized Lubrication: The bearing is pre-lubricated (PH), ensuring immediate startup protection and reliable operation within a temperature range of -30°C to 110°C.
- Robust Material: Constructed from chrome steel for both rings and balls, ensuring high durability, wear resistance, and a long service life under demanding conditions.
7308 BEGAPH Bearing Typical Application Areas
The 7308 BEGAPH is ideally suited for high-performance applications across various industries, including:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers requiring precision and rigidity.
- Electric Motors & Generators: As a locating bearing to handle axial thrust loads.
- Pumps and Compressors: Where reliable performance under combined radial and axial loads is essential.
- Precision Gearboxes: Providing accurate shaft positioning and supporting gear thrust forces.
- Agricultural and Construction Machinery: In applications demanding robust performance and high load capacity.
