7320 BEGAP Bearing Product Overview & Core Advantages
The 7320 BEGAP is a single row angular contact ball bearing engineered for precision performance in demanding applications. This metric bearing features a 40° contact angle optimized to handle significant combined loads—simultaneously supporting high radial loads and unidirectional axial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and rotational stability. The open design with nylon cage enables high-speed operation up to 4,000 rpm, while its generous load points distance (90 mm) provides superior moment load resistance. These characteristics make it ideal for applications requiring high rigidity and precise shaft positioning.

7320 BEGAP Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway curvature enable superior load distribution, handling dynamic radial loads up to 48,600 lbf and static radial loads up to 46,800 lbf.
High-Speed Nylon Cage: The lightweight nylon cage reduces centrifugal forces, minimizes friction, and contributes to the bearing's exceptional high-speed capability of 4,000 rpm while providing excellent guidance and stability.
Precision Manufacturing: Manufactured to P6 tolerance standards with tight dimensional controls (bore: -0.015mm to 0, OD: -0.02mm to 0), ensuring consistent performance and precise shaft alignment in critical applications.
Material Excellence: Constructed from high-grade chrome steel for both rings and balls, providing excellent wear resistance, dimensional stability, and long service life under demanding operating conditions.
