7317 BEP Bearing Product Overview & Core Advantages
The 7317 is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. This metric bearing features a 40° contact angle, optimized for carrying significant axial loads in one direction while simultaneously handling radial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy. Its open design allows for customized lubrication solutions, making it ideal for high-speed spindles and other precision machinery where superior rotational accuracy and high rigidity are paramount.

7317 BEP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated shoulder diameters (inner ring: 122.3mm/103.03mm, outer ring: 144.95mm) are engineered to provide superior axial load capacity and operational stability.
High-Speed Capability: The nylon cage ensures low friction and excellent guidance at high rotational speeds, contributing to a limiting speed of 4,300 rpm. The open design facilitates efficient heat dissipation.
Exceptional Load Ratings: With a dynamic load rating of 32,850 lbf and a static load rating of 27,450 lbf, this bearing is built to handle demanding combined radial and axial loads.
Precision Engineering: Manufactured from chrome steel for both rings and balls, and held to strict P6 tolerance, it guarantees high running accuracy and long-term dimensional stability.
7317 BEP Bearing Typical Application Areas
- Machine Tool Spindles: Ideal for high-precision milling, grinding, and turning centers requiring high rigidity and speed.
- High-Speed Motors and Pumps: Suitable for applications where rapid rotation and axial load capacity are critical.
- Precision Gearboxes: Used in transmissions to support shafts under combined loads.
- Industrial Compressors and Fans: Provides reliable performance in equipment with significant axial thrust.
