7307 BECBY Bearing Product Overview & Core Advantages
The 7307 BECBY is a single row angular contact ball bearing designed for high-performance applications requiring exceptional precision and reliability. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 40° contact angle for superior axial load capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers high running accuracy and is pre-lubricated for immediate operation. Its compact design with a 35 mm bore and 21 mm width makes it ideal for space-constrained, high-rigidity applications.
7307 BECBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| BE | Increased internal clearance and contact angle (40°) | Optimized for high axial loads and thermal expansion management |
| CB | Specific internal design and clearance | Balanced performance for combined load conditions |
| Y | Special cage design and material (Brass) | Enhanced high-speed capability and cage stability |
7307 BECBY Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle provides excellent resistance to axial loads from one direction while handling significant radial loads. The optimized raceway and ball geometry contribute to a high dynamic load rating of 9338 lbf and static load rating of 5962 lbf.
- Precision Performance: Manufactured to P6 (ABEC-3) tolerance class with tight bore and outside diameter tolerances, ensuring high running accuracy, reduced vibration, and predictable performance in precision machinery.
- High-Speed Capability: The brass cage (Y suffix) ensures stability and low friction at high rotational speeds, supporting a limiting speed of 11,000 rpm. The open design facilitates efficient lubrication management.
- Material & Durability: Constructed from chrome steel for both rings and balls, providing high hardness, wear resistance, and long service life under demanding operating conditions within a temperature range of -30°C to 110°C.
7307 BECBY Bearing Typical Application Areas
The 7307 BECBY is ideally suited for applications requiring high precision, speed, and reliable axial load handling:
- Machine Tool Spindles
- High-Speed Pumps and Compressors
- Precision Gearboxes
- Industrial Robotics and Automation
