7326 BM Bearing Product Overview & Core Advantages
The 7326 BM is a single row angular contact ball bearing engineered for precision applications requiring high performance under combined loads. Its defining feature is the 40° contact angle, which provides exceptional capacity for handling substantial axial loads in one direction while simultaneously supporting radial loads. Manufactured to a P6 (ABEC-3) tolerance class, this bearing ensures high running accuracy and reliability. The brass cage contributes to stable operation at high speeds, making it an ideal choice for demanding, high-rigidity applications where precision is paramount.
7326 BM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7326 | Standard bearing designation indicating a metric single row angular contact ball bearing with a 130 mm bore, 280 mm OD, and 58 mm width. |
| B | Signifies a 40° contact angle, which provides higher axial load capacity compared to standard angular contact bearings. |
| M | Indicates the bearing is supplied with brass (copper alloy) cage, offering superior strength and guidance for high-speed applications. |
7326 BM Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The 40° contact angle and robust internal geometry enable the bearing to handle significant combined radial and axial loads efficiently. With a dynamic load rating of 62,100 lbf and static load rating of 68,625 lbf, it is built for durability.
- High-Speed Performance: The precision-machined brass cage ensures excellent stability and low friction, allowing for a limiting speed of 3,400 rpm. This makes it suitable for high-velocity spindles and machinery.
- Precision & Rigidity: Manufactured to P6 tolerance with strict dimensional controls on bore, outside diameter, and width, this bearing provides high running accuracy and system rigidity, minimizing deflection under load.
- Material Integrity: Constructed from chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and long service life under demanding operating conditions.
7326 BM Bearing Typical Application Areas
The 7326 BM is designed for high-performance machinery and systems, including:
- Machine Tool Spindles: Provides high precision and rigidity for milling, grinding, and turning centers.
- High-Speed Pumps & Compressors: Handles combined loads and high rotational speeds reliably.
- Precision Gearboxes: Ensures accurate shaft positioning and load support in industrial transmissions.
- Material Handling Equipment: Used in high-capacity applications requiring robust bearing performance.
