Abstract

A bearing location for rotatably supporting a shaft on a carrier structure about a rotation axis may include a bearing opening disposed in the carrier structure. The bearing opening may include an cylindrical inner bearing face on an inner periphery arranged coaxially with the rotation axis. The inner bearing face may interact with a cylindrical outer bearing face disposed on an outer periphery of the shaft. An annular seal may be arranged coaxially with the rotation axis and may include a labyrinth seal have at least one annular rib and at least one annular groove. An inner sealing gap and an outer sealing gap may be disposed radially between walls of the rib and walls of the groove. The inner sealing gap and the outer sealing gap may each extend annularly and may be arranged coaxially with the rotation axis.
