7318 BEGAY Bearing Product Overview & Core Advantages
The 7318 BEGAY is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. This precision bearing is designed to accommodate combined loads, primarily handling significant axial loads in one direction while also supporting substantial radial loads. Its 40° contact angle and P6 (ABEC-3) tolerance class ensure high running accuracy and operational stability. Manufactured from high-grade chrome steel with a brass cage, it is optimized for demanding environments, offering a superior balance of high-speed capability, load capacity, and long service life.
7318 BEGAY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7318 | Standard bearing series designation indicating a metric bore diameter of 90 mm, outside diameter of 190 mm, and width of 43 mm. |
| BE | Designates a 40° contact angle, which provides a high thrust load capacity. |
| GA | Indicates special internal design and optimized internal clearance for preload and high rigidity. |
| Y | No specific suffix provided in the data, but typically denotes a modification to standard. In this context, it is part of the specific performance grade designation. |
7318 BEGAY Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single row design with a 40° contact angle and P6 tolerance class delivers high system rigidity and precise rotational accuracy, essential for applications with minimal deflection.
- Superior Load Capacity: Engineered to handle high axial loads in one direction and substantial radial loads simultaneously. With a dynamic load rating of 37,350 lbf and a static load rating of 32,850 lbf, it is built for durability under combined loads.
- Optimized High-Speed Performance: The brass cage ensures stability and reduced friction at high rotational speeds, supporting a limiting speed of 4,500 rpm.
- Robust Material Construction: Components made from chrome steel offer high hardness, wear resistance, and dimensional stability across a wide temperature range of -30°C to 110°C.
- Pre-lubricated for Immediate Use: The bearing comes lubricated from the factory, reducing initial setup time and ensuring smooth operation from the start.
