RBC Bearings 4NBF614YJ Airframe Control Needle Roller Bearing

RBC Bearings 4NBF614YJ is an airframe control needle roller bearing from the NBF series, designed for aerospace control linkages with a 0.2500 in bore. Its nominal outer diameter is about 0.8750 in and width about 0.3750 in, with SAE AS24465–compliant dimensions for this airframe bearing family. The open needle roller design yields a compact, low-profile package suitable for flight-control actuators and linkage assemblies where high stiffness and precise guidance are required. Exposed surfaces may receive protective plating to guard against corrosion in aerospace environments, per RBC’s airframe control bearing guidelines.
