7317 BECBF Bearing Product Overview & Core Advantages
The 7317 BECBF is a single row angular contact ball bearing designed for high-performance applications requiring exceptional precision and reliability. This precision bearing excels at handling combined loads, simultaneously supporting significant radial loads and unidirectional axial loads. Its optimized 40° contact angle and P6 (ABEC-3) tolerance class ensure high running accuracy and rotational stability, making it ideal for demanding, high-speed machinery. The bearing is pre-lubricated for immediate operation and features a robust stainless steel cage for enhanced durability.
7317 BECBF Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| BE | Increased internal clearance and 40° contact angle | Optimized for high axial load capacity and high-speed operation. |
| CB | Specific internal design and clearance | Provides consistent operational performance under predefined conditions. |
| F | Machined brass cage (compatible with high-speed performance) | Offers high strength, excellent wear resistance, and suitability for high limiting speeds. |
7317 BECBF Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a generous contact angle of 40° provides superior rigidity and is engineered to handle significant combined radial and axial loads in one direction efficiently.
- High-Speed Performance: The machined brass (F suffix) cage ensures dimensional stability and low friction at high rotational velocities, contributing to a high limiting speed of 4,300 rpm.
- Precision Engineering: Manufactured to a P6 (ABEC-3) tolerance class with tight dimensional control on the bore diameter (85 mm) and outside diameter (180 mm), guaranteeing high running accuracy and minimal vibration.
- Durability & Reliability: Constructed from chrome steel for rings and balls, this bearing offers excellent fatigue resistance and a long operational life, even under continuous load.
