7330 BGAM Bearing Product Overview & Core Advantages
The 7330 BGAM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) tolerance class, making it ideal for applications demanding exceptional running accuracy and high rigidity. Its optimized internal geometry enables it to efficiently handle significant radial loads combined with substantial axial loads in one direction, while its brass cage ensures reliable operation at elevated speeds. The bearing comes pre-lubricated for immediate installation and long-term performance.

7330 BGAM Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with 40° contact angle provides exceptional stiffness and enables the bearing to withstand significant combined radial and axial loads. With a radial dynamic load rating of 74,700 lbf and static load rating of 87,750 lbf, this bearing delivers reliable performance in demanding applications.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with precise dimensional control, the 7330 BGAM ensures minimal runout and consistent performance. The carefully calculated shoulder diameters (outer ring: 258.65 mm, inner ring large-side: 216.1 mm) provide optimal support for accurate positioning.
High-Speed Performance: The brass cage (M suffix) enables stable operation at the limiting speed of 2,800 rpm, while the optimized internal geometry minimizes friction and heat generation. The pre-lubrication ensures proper lubrication throughout the operating temperature range of -30° to 110°C.
Robust Construction: Manufactured from chrome steel for both rings and balls, this bearing offers excellent wear resistance and durability. The 4 mm chamfer dimension facilitates easier installation and proper seating in housing arrangements.
