7307 BEGAP Bearing Product Overview & Core Advantages
The 7307 BEGAP is a single row angular contact ball bearing designed for exceptional performance in precision applications. This metric bearing features a P6 (ABEC-3) tolerance class, ensuring high running accuracy and dimensional stability. Its optimized 40° contact angle enables it to support significant combined loads—simultaneously handling radial forces and thrust loads in one direction. The nylon cage contributes to smooth operation at high speeds, while the pre-lubricated design ensures immediate readiness for installation. With its high rigidity and precise bearing dimensions (35mm bore, 80mm OD), the 7307 BEGAP is engineered for applications demanding reliability and precision.

7307 BEGAP Bearing Structural Features & Performance Benefits
Optimized Contact Geometry: The 40° contact angle provides excellent thrust capacity while maintaining substantial radial load capability, making it ideal for combined load applications.
High-Speed Capability: The nylon cage reduces friction and enables smooth operation at the limiting speed of 11,000 rpm, while the optimized internal geometry minimizes heat generation.
Precision Performance: Manufactured to P6 tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring precise shaft positioning and minimal runout.
Robust Construction: Made from chrome steel for both rings and balls, providing high fatigue resistance and durability under demanding operating conditions.
Pre-lubricated Design: Factory lubricated for immediate operation, suitable for the specified temperature range of -30° to 110°C.
