7306 BEGAP Bearing Product Overview & Core Advantages
The 7306 BEGAP is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its defining feature is the 40° contact angle, which provides exceptional capacity for handling substantial axial loads in one direction, in addition to radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures high running accuracy and reliability. The optimized internal geometry, combined with a lightweight nylon cage, contributes to its high limiting speed of 13,000 rpm, making it an ideal solution for demanding, high-speed machinery.
7306 BEGAP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7306 | Basic bearing designation indicating a metric, single row angular contact ball bearing with a 30 mm bore diameter. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| GA | Indicates the bearing is supplied with a light preload for enhanced rigidity and precise shaft positioning. |
| P | Specifies the P6 tolerance class (equivalent to ABEC-3), ensuring high precision and dimensional stability. |
7306 BEGAP Bearing Structural Features & Performance Benefits
- High Axial Load Capacity: The 40° contact angle is the primary design feature that enables this bearing to support high one-direction axial loads efficiently, making it suitable for applications like machine tool spindles.
- High-Speed Capability: The use of a nylon cage reduces centrifugal forces and friction, allowing for a high limiting speed and smooth operation at up to 13,000 rpm.
- Precision and Rigidity: Manufactured to P6 precision tolerance and supplied with a preload (GA), this bearing offers high running accuracy, minimal runout, and increased system rigidity.
- Optimal Lubrication: The bearing comes pre-lubricated, ensuring immediate startup protection and reliable operation within a temperature range of -30°C to 110°C.
7306 BEGAP Bearing Typical Application Areas
The 7306 BEGAP is designed for high-performance applications where precision, speed, and axial load capacity are critical. Typical uses include:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Gearboxes
- Pumps and Compressors
- Agricultural Machinery
