RBC Bearings Incorporated KP12AFS464 Ball Bearing

RBC KP12AFS464 is a KP‑A Series airframe control ball bearing—an aerospace‑grade, single‑row radial bearing designed for compact, high‑reliability actuation in airframe assemblies. It features a 0.75 in bore (3/4 in), an outside diameter of 1.625 in (1‑5/8 in), and a width of 0.437 in (11.1 mm), delivering a light footprint without sacrificing stiffness. The bearing is double‑sealed and cadmium plated, manufactured from SAE‑52100 bearing‑quality steel, and weighs about 0.14 lb, with a radial load rating of 8,790 lbf to handle demanding control‑system loads. Its design is specified as single‑row, non‑fill slot with no cage, aligning with RBC’s airframe control bearing family used in aircraft control linkages and actuators where space is tight and sealed protection is essential. The KP12AFS464 designation identifies a standard airframe bearing configuration suitable for aerospace applications and compatible with SAE‑AS27641 requirements.
