RBC Bearings 10NBL2426YJ Needle Roller Bearing

RBC Bearings' 10NBL2426YJ is an airframe control needle roller bearing in the RBC NBL series, a track-type bearing optimized for aerospace actuation and control linkages. It features a 0.625 in bore, 1.625 in outer diameter, and 1.50 in width, with an open design and a mounting hole on the outer ring for installation and no flange. The bearing is manufactured from 52100 bearing-quality steel, cadmium plated, and weighs approximately 0.69 lb. It carries a load rating of 19,900 lbf and is specified for operating temperatures from 0 to +250 °F, with a speed rating noted at 100 rpm in RBC/NBL data. The NBL family is designed to deliver high radial-load capacity in a compact footprint, making it well-suited for space-constrained airframe applications. RBC notes that airframe needle roller bearings have been used in helicopter rotor-head assemblies, including the Boeing CH-47, highlighting their role in critical aerospace mechanisms.
