7311 BEGAY Bearing Product Overview & Core Advantages
The 7311 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, efficiently handling significant radial loads and unidirectional axial loads simultaneously. Its optimized 40° contact angle provides superior axial rigidity, making it an ideal choice for arrangements where high rotational accuracy and stability are critical. Manufactured to P6 (ABEC-3) tolerance class, it ensures consistent performance in demanding operational environments.
7311 BEGAY Bearing Model Code Explained, Specifications & Naming Convention
- 7311: Basic designation indicating a metric series angular contact ball bearing with a 55 mm bore and 120 mm outside diameter.
- BE: Denotes a 40° contact angle and an optimized internal design for increased load capacity.
- GA: Signifies a special preload class for enhanced rigidity and precise rotational performance.
- Y: Indicates that the bearing is furnished with a brass cage, which offers excellent strength and is suitable for high-speed operation.
7311 BEGAY Bearing Structural Features & Performance Benefits
The 7311 BEGAY's construction delivers distinct performance advantages:
- High Rigidity and Load Capacity: The single row design with a robust brass cage and a 40° contact angle provides high axial rigidity and enables the bearing to support substantial combined radial and axial loads.
- Precision Performance: Manufactured to P6 tolerance class, this bearing guarantees minimal runout and high running accuracy, which is essential for precision machinery.
- High-Speed Capability: The lightweight and durable brass cage (Y) contributes to stable operation at high rotational speeds, with a limiting speed of 7,000 rpm.
- Material Integrity: Constructed from chrome steel for both rings and balls, the bearing ensures high durability, wear resistance, and a long operational lifespan under demanding conditions.
