7328 BGAM Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row design with a 40° contact angle provides excellent rigidity and enables the bearing to support substantial combined loads. With a dynamic load rating of 67,950 lbf and static load rating of 77,625 lbf, it delivers reliable performance under heavy-duty conditions.
High-Speed Performance: The brass cage (M) ensures stable operation at high rotational speeds, supporting a limiting speed of 3,000 rpm. The optimized internal geometry minimizes friction and heat generation.
Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees precise shaft positioning and smooth operation, critical for high-precision applications.
Material Quality: Constructed from chrome steel rings and balls with a brass cage, offering excellent durability and wear resistance.
