Engine bearings are rolling-element and plain bearing assemblies designed specifically for gas turbine and reciprocating aero-engine applications, covering main shaft, accessory gearbox, and spool support positions; they encompass high-speed ball and roller configurations manufactured to ABEC/RBEC tolerance classes, utilising M50 and M62 bearing steels, silver-plated cages, and MIL-PRF-23699 lubricant-compatible surface treatments to withstand extreme rotational speeds, thermal cycling, and combined radial and axial loading.
