Claim 0:
1. A rotor support configured to rotatably mount a rotor shaft in a vacuum pump, said rotor support comprising:
a rolling bearing for rotatably supporting said shaft;
an insert and at least one resilient damping member, said insert and said at least one resilient damping member surrounding said rolling bearing; wherein
said insert comprises inner and outer annular portions connected by a plurality of flexible members, said plurality of flexible members being configured to flex in a radial plane and resist movement in an axial plane, thereby absorbing radial movement of said shaft; and
said at least one resilient damping member is formed of an elastomeric material configured to flex in both a radial and axial direction; wherein
said at least one resilient damping member is configured to support said insert and is in at least one of the following configurations with said insert:
at least one of said at least one resilient damping member is located between said inner annular portion of said insert and said rolling bearing; and
said outer annular portion of said insert is located between at least one of said at least one resilient damping member and said rolling bearing.
