7309 BEGBY Bearing Product Overview & Core Advantages
The 7309 BEGBY is a single row angular contact ball bearing engineered for applications requiring high precision and the ability to accommodate combined loads. This bearing is specifically designed to handle significant axial loads in one direction while simultaneously supporting radial loads, making it ideal for high-rigidity arrangements. Manufactured to a P6 (ABEC-3) tolerance class and featuring a robust brass cage, it delivers reliable performance in demanding operational environments. Its optimized 40° contact angle and pre-lubrication ensure smooth operation and long service life.
7309 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7309 | Basic bearing designation indicating a metric, single row angular contact ball bearing with a 45 mm bore diameter. |
| BE | Designates a 40° contact angle and increased internal radial clearance, optimized for high axial load capacity. |
| GB | Indicates the bearing is supplied with a pre-lubrication of high-performance grease. |
| Y | Specifies the use of a brass cage, providing high strength and excellent guidance for high-speed applications. |
7309 BEGBY Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 40° contact angle is optimized to support high axial loads in one direction and substantial radial loads simultaneously. The calculated shoulder diameters on both rings ensure secure axial location, contributing to overall system stiffness.
- Precision & High-Speed Performance: Manufactured to P6 tolerance class for precise running accuracy. The brass cage (Y) ensures stable operation and is suitable for the specified limiting speed of 9,000 rpm.
- Durability & Reliability: Components are made from chrome steel for high load ratings (C = 13,725 lbf, C0 = 9,112 lbf). The bearing is pre-lubricated (GB) for immediate use and reliable operation within a temperature range of -30°C to 110°C.
- Standard Dimensions: Features a compact cross-section with a bore of 45 mm, outside diameter of 100 mm, and width of 25 mm, making it easy to integrate into standard designs.
7309 BEGBY Bearing Typical Application Areas
