Abstract
Systems and methods are disclosed herein for bearings in a gas turbine engine. A bearing system may include a squirrel cage and a bearing support cage coupled to the squirrel cage. The bearing support cage may include an outer race and a fenestrated cone. The bearing support cage may include a support cage anti-rotation tab adjacent to the outer race. The bearing system may include a housing coupled to the squirrel cage. The housing may include a housing anti-rotation tab. The support cage anti-rotation tab and the housing anti-rotation tab may prevent the bearing system from twisting.
