7307 BECBP Bearing Product Overview & Core Advantages
The 7307 BECBP is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. This metric bearing is distinguished by its ability to support significant radial loads and unidirectional axial loads simultaneously, thanks to its defined 40° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it offers high running accuracy, making it an ideal choice for high-speed spindles and other precision machinery where rigidity and operational stability are critical.
7307 BECBP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7307 | Basic bearing designation indicating a medium series, angular contact ball bearing with a 35 mm bore diameter. |
| BE | Designates a 40° contact angle and an optimized internal design for high axial load capacity. |
| CBP | Indicates a Nylon (Polyamide) cage, pressed from sheet steel. This cage design contributes to lower friction, reduced weight, and is suitable for high-speed operation. |
7307 BECBP Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of the Nylon CBP cage and an open design allows for efficient lubrication and heat dissipation, supporting a high limiting speed of 11,000 rpm.
- Superior Load Capacity: The 40° contact angle and robust construction of Chrome Steel rings and balls provide excellent resistance to combined (radial and axial) loads, with a dynamic load rating of 9338 lbf.
- High Precision & Rigidity: Manufactured to P6 tolerance with precise raceway and shoulder geometries, this bearing ensures minimal runout and high system rigidity, which is vital for accurate positioning.
- Optimized Lubrication: The bearing is supplied lubricated, ready for immediate use within its specified temperature range of -30°C to 110°C.
7307 BECBP Bearing Typical Application Areas
This bearing is commonly specified in demanding sectors such as:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Material Handling Equipment
- Agricultural and Construction Machinery
