| Code | Interpretation | Technical Significance |
|---|---|---|
| 7411 | Basic Designation | Indicates a metric series, single row angular contact ball bearing with a 55mm bore, 140mm OD, and 33mm width. |
| B | Contact Angle | Denotes a 40° contact angle, optimized for supporting high axial loads in one direction. |
| M | Cage/Cage Material | Signifies a brass cage, which offers excellent durability, high-speed capability, and guidance stability. |
7411 BM Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single row design with a P6 tolerance class ensures precise shaft positioning and minimal runout, critical for applications requiring high rotational accuracy. The calculated load point distance (57.8 mm) contributes to stable moment load capacity.
- Superior Load Capacity: Engineered with a 40° contact angle, this bearing is adept at handling combined radial and axial loads. It boasts a high dynamic load rating of 24,975 lbf and a static load rating of 17,212 lbf.
- Optimized High-Speed Performance: The use of a brass cage (M) allows for a limiting speed of 8,000 rpm. The open design facilitates efficient lubrication management, reducing friction and heat generation at high velocities.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing provides high hardness, wear resistance, and a long operational lifespan under demanding conditions.
7411 BM Bearing Typical Application Areas
The 7411 BM is ideally suited for machinery and systems where precision, speed, and reliability are paramount. Key sectors include:
- Machine Tool Spindles: For high-speed milling, grinding, and turning centers.
- Precision Gearboxes: Especially in industrial robotics and automation systems.
- Pumps and Compressors: Where reliable performance under combined loads is essential.
- Agricultural and Construction Machinery: In transmissions and wheel hubs.
- Electric Motors: For applications requiring high-speed operation and axial load support.
