7318 BEGAM Bearing Product Overview & Core Advantages
The 7318 BEGAM is a precision angular contact ball bearing designed for applications requiring high rotational accuracy and exceptional rigidity. As a single row bearing with a steep 40° contact angle, it excels at supporting combined loads, particularly heavy thrust loads in one direction. Its P6 (ABEC-3) tolerance class ensures reliable performance in high-speed and high-precision machinery, making it an ideal component for demanding industrial environments.
7318 BEGAM Bearing Model Code Explained, Specifications & Naming Convention
- 7318: Basic designation indicating a metric angular contact ball bearing with a 90mm bore, 190mm OD, and 43mm width.
- B: Denotes a 40° contact angle, optimized for high thrust load capacity.
- E: Signifies an optimized internal design with increased ball complement and reinforced structure for higher load ratings.
- G: Indicates the use of a brass cage, which provides excellent durability and is suitable for high-speed operation.
- A: Specifies that the bearing is lubricated with a high-performance grease from the factory.
- M: Designates that the bearing is supplied as a single, unmounted unit.
7318 BEGAM Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The single row design with a 40° contact angle and optimized internal geometry (E-design) provides superior stiffness and enables the bearing to handle significant radial and axial loads simultaneously. The brass cage (G) ensures stable operation under high centrifugal forces.
High-Speed Performance: The combination of the precision P6 tolerance, robust brass cage, and pre-applied lubrication allows for a high limiting speed, making it suitable for demanding rotational applications.
Precision and Reliability: Manufactured from chrome steel for both rings and balls, this bearing offers consistent performance and long service life. The specified load ratings and dimensional tolerances guarantee predictable behavior in critical applications.
