7306 BECBY Bearing Product Overview & Core Advantages
The 7306 BECBY is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Its design is optimized to simultaneously support significant radial loads and substantial axial loads in one direction, making it an ideal component for systems demanding high rigidity and operational accuracy. Manufactured to P6 (ABEC-3) tolerance class with a 40° contact angle, this bearing delivers exceptional running accuracy and stability. The open design, combined with a robust brass cage, facilitates high-speed operation, while its pre-lubrication ensures immediate readiness for service across a wide temperature range from -30°C to 110°C.
7306 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Interpretation |
|---|---|
| 7306 | Standard bearing series designation indicating a metric, single row bearing with a 30 mm bore diameter, 72 mm outside diameter, and 19 mm width. |
| BE | Signifies an increased internal design with a 40° contact angle and optimized internal geometry for high axial load capacity. |
| CB | Indicates a P6 (ABEC-3) tolerance class for high running accuracy and dimensional precision. |
| Y | Denotes a special cage design, in this case a brass cage, which provides high strength, excellent guidance, and suitability for high-speed applications. |
7306 BECBY Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design with a 40° contact angle and robust construction provides high rigidity, enabling the bearing to handle significant combined radial and axial loads efficiently. The optimized shoulder diameters on both rings ensure secure seating and maximum load support.
- High-Speed Performance: The lightweight and durable brass cage minimizes centrifugal forces and ensures stable ball guidance, contributing to a high limiting speed of 13,000 rpm. The open design reduces friction and heat generation.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees precise internal clearances and dimensional stability, which is critical for applications requiring minimal runout and vibration.
- Ready-to-Install and Durable: The bearing is pre-lubricated, providing immediate protection and smooth operation from startup. The use of high-grade chrome steel for rings and balls ensures long service life and reliable performance under demanding conditions.
