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.
