7211 BEGBY Bearing Product Overview & Core Advantages
The 7211 BEGBY 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 substantial axial loads in one direction while also supporting radial loads. Its optimized 40° contact angle and P6 (ABEC-3) tolerance class ensure superior running accuracy and rotational stability. The brass cage contributes to smooth operation at high speeds, making it an ideal solution for demanding machinery where high rigidity and dependable performance are critical.
7211 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7211 | Basic bearing designation indicating a metric series with a 55 mm bore diameter and 100 mm outside diameter. |
| BE | Designates a 40° contact angle and an optimized internal design for increased axial load capacity. |
| GB | Indicates the bearing is supplied with a lubricant from the factory. |
| Y | Specifies a brass cage, which is beneficial for high-speed applications and offers excellent dimensional stability. |
7211 BEGBY Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a steep 40° contact angle is optimized to handle high one-direction axial loads and moderate radial loads simultaneously. The precisely calculated shoulder diameters on both rings provide robust support, enhancing the bearing's overall stiffness.
- High-Speed Performance: The brass cage (Y) ensures low friction, excellent guidance, and high mechanical strength, enabling reliable operation at the specified limiting speed of 8,000 rpm.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class, this bearing guarantees minimal runout and vibration, which is crucial for applications requiring high rotational accuracy.
- Durability and Compliance: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. It is compliant with ROHS and REACH environmental directives.
