RBC Bearings 4NBF614YJ Needle Roller Bearing

RBC Bearings 4NBF614YJ Airframe Control Needle Roller Bearing is an open, needle-roller bearing in RBC’s NBF airframe series designed for aerospace control applications where space is at a premium. It features a 0.2500 in bore, a 0.8750 in outer diameter (7/8 in), and a 0.3750 in width, delivering a compact cross-section for space-constrained control linkages. This bearing is rated for a static radial load of approximately 1,910 pounds and is specified to SAE AS24465 airframe bearing requirements, ensuring compatibility with common aerospace hardware. Manufactured by RBC Bearings Incorporated, the 4NBF614YJ is part of a family of airframe needle bearings that prioritizes high load capacity relative to cross-section in demanding flight-control and actuation assemblies. With its needle-roller design, it provides high radial load capacity in a small footprint, making it well suited for linkages, actuators, and other control-surface mechanisms in aircraft where weight and space matter.
