摘要： A seal assembly is provided that extends along an axial centerline. The seal assembly includes a seal support, a seal housing, a plurality of torque pins and a plurality of stopper collars. The seal housing includes a plurality of slots arranged circumferentially around the centerline. The slots extend axially through the seal housing, and one or more of the slots has a lateral slot width. The torque pins are connected to the seal support. Each of the torque pins respectively extends axially through a uniquely associated one of the slots to a distal pin end. Each of the stopper collars is uniquely associated with and connected to a respective one of the torque pins at the pin end. One or more of the stopper collars has a lateral collar width that is less than the slot width.

摘要： A bearing system is provided for a gas turbine engine. This bearing system includes a spring defined about an axis of rotation. The spring has a multiple of beams which extend between a flange and a damper attachment. A damper defined about the axis of rotation and mounted to the spring to at least partially axially overlap the multiple of beams.
