7310 BEGAPH Bearing Product Overview & Core Advantages
The 7310 is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. Designed with a 40° contact angle, this bearing excels at handling significant axial loads in one direction while simultaneously supporting radial loads. Its P6 (ABEC-3) tolerance class ensures exceptional running accuracy and dimensional stability, making it ideal for applications demanding high rigidity and precise rotational control. The open design, combined with nylon cage construction, facilitates high-speed operation up to 8,000 rpm.

7310 BEGAPH Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precision-ground raceways provide superior axial load capacity while maintaining excellent radial load performance. This design ensures high rigidity and minimal deflection under combined loading conditions.
High-Speed Capability: The nylon cage reduces friction and weight, enabling limiting speeds of 8,000 rpm. The open construction allows for efficient heat dissipation and optimal lubricant flow.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls on bearing dimensions (bore: 50mm, OD: 110mm, width: 27mm), ensuring consistent performance and easy installation in precision assemblies.
Material Excellence: Chrome steel rings and balls provide high hardness and wear resistance, while the nylon cage offers quiet operation and reduced maintenance requirements.
