RBC Bearings 4NBF614YJ Airframe Control Needle Roller Bearing

RBC Bearings 4NBF614YJ Airframe Control Needle Roller Bearing is a compact, aerospace-grade track roller from the RBC NBF series, designed for airframe control linkages and actuators where a small cross-section must carry high radial loads. It features a 0.2500 in bore, a nominal outer diameter of 0.8750 in (7/8 in), and a width of 0.3750 in, and it is specified under SAE AS24465 for airframe bearings. The needle-roller construction concentrates load capacity in a slim envelope, delivering robust radial support in confined spaces typical of aircraft control hardware. Applications include flight-control actuators, control linkages, and other airframe control assemblies where precise, durable rolling elements are required in demanding aerospace environments.
