A vacuum pump comprises a housing, a drive shaft supported by a bearing a rrangement for rotation relative to the housing about an axis, and a pumping mechanism comprising a stator component mounted on the housing and a disk-s haped rotor component mounted on the drive shaft axially proximate the stato r component. The bearing arrangement comprises a bearing supported in both r adial and axial directions by a resilient support, comprising inner and oute r annular portions connected by a plurality of flexible members, so that the re is a fixed relation between the inner race of the bearing and the outer p ortion of the resilient support to determine the axial clearance between the rotor and stator components of the pumping mechanism.
