7311 BEGBY Bearing Product Overview & Core Advantages
The 7311 BEGBY is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional rigidity and high-speed performance. Designed to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 40° contact angle optimized for handling significant thrust loads in one direction. Its precision P6 (ABEC-3) tolerance ensures reliable operation in demanding industrial environments where accuracy and rotational precision are critical.
7311 BEGBY Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| BE | Increased contact angle (40°) | Enhanced axial load capacity |
| GB | Optimized internal geometry | Improved load distribution and reduced stress |
| Y | Brass cage construction | Superior high-speed stability and durability |
7311 BEGBY Bearing Structural Features & Performance Benefits
High Rigidity Design: The single row construction with optimized raceway geometry and 40° contact angle provides exceptional stiffness, minimizing deflection under heavy combined loads.
Superior Load Capacity: Rated for 19,125 lbf dynamic and 13,500 lbf static radial loads, this bearing handles significant angular contact thrust loads efficiently.
High-Speed Performance: The brass cage (Y suffix) ensures stable operation at limiting speeds up to 7,000 rpm, while the open design facilitates efficient lubrication.
Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional controls (bore tolerance: -0.012mm to 0), ensuring consistent performance in precision applications.
