A vacuum pump, in particular a turbomolecular pump or a multi-inlet pump, includes a rotor shaft (12) that supports at least one rotor device (14). The rotor shaft (12) is mounted on the pressure side by way of a bearing arrangement (56) and on the suction side by way of a bearing arrangement (30). The suction-side bearing arrangement (30) is disposed in a high-vacuum area (22) and includes an electromagnetic bearing. Preferably, a coil (32) of the electromagnetic bearing is disposed in a recess (38) of a housing element (40). The recess (38) is pressure-encapsulated, in particular by a tubular closure element (42).
