The invention relates to a stator assembly (1) for a camshaft adjuster (2), comprising a stator (3) the exterior (5) of which has a toothed portion (4) for absorbing torque provided by a crankshaft. The stator (3) comprises a wall (6) which integrally forms the toothed portion (4) and has an axially running cavity (7) for receiving a rotor (9). At least one flange section (8) of the stator (3), which protrudes radially inwards, forms an axial stop for the rotor (9). A spacer disk (10) which is separate from the stator (3) and the rotor (9) is present in the cavity (7) and sealingly rests on the flange section (8). The invention also relates to a van-type hydraulic camshaft adjuster which comprises a rotor and a stator assembly of the above type.
