7213 BEGAF Bearing Product Overview & Core Advantages
The 7213 BEGAF is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. Designed with a 40° contact angle, this bearing excels at supporting substantial axial loads in one direction while simultaneously handling radial loads. Manufactured to P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability. Its optimized internal geometry and premium materials deliver superior high-speed capability and operational stability, making it an ideal choice for demanding industrial machinery.
7213 BEGAF Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7213 | Standard bearing series designation indicating a metric, single row angular contact ball bearing with a 65mm bore, 120mm OD, and 23mm width. |
| BE | Designates a 40° contact angle and optimized internal design for high axial load capacity. |
| GA | Indicates the bearing is pre-lubricated with a specific high-performance grease. |
| F | Signifies the bearing is manufactured to a P6 tolerance class (equivalent to ABEC-3) for high precision. |
7213 BEGAF Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle provides excellent rigidity and is specifically engineered to handle high axial loads in one direction combined with radial loads. The robust construction ensures stable operation under demanding conditions.
- High-Speed Performance: The stainless steel cage and optimized internal geometry contribute to low friction and heat generation, enabling a high limiting speed of 6,300 rpm. This makes it suitable for high-speed applications.
- Precision and Longevity: Manufactured to P6 precision class with tight dimensional tolerances, this bearing guarantees smooth and accurate rotation. The pre-lubrication reduces initial friction and wear, enhancing service life.
- Material Excellence: Components made from chrome steel (rings and balls) and a stainless steel cage offer high strength, wear resistance, and corrosion protection, ensuring reliability across a temperature range of -30°C to 110°C.
7213 BEGAF Bearing Typical Application Areas
The 7213 BEGAF is ideally suited for precision machinery and systems requiring high speed and axial load capacity. Common applications include:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Robotics and Automation Equipment
- Agricultural and Construction Machinery
