A bearing assembly for mounting a rotatable shaft of a pump and the pump are disclosed. The bearing assembly comprises: a bearing comprising an outer ring and an inner ring; a bearing support configured to support the outer ring of the bearing, the bearing support surrounding at least a portion of an outer surface of the outer ring extending across at least a portion of one end surface of the outer ring; and a shield extending from the bearing support towards the inner ring to thereby obscure at least a portion of an annular gap between the inner and outer ring.

Bearing assembly for a pump and a pump comprising the bearing assembly

The present disclosure relates to a rotor assemblyfor a turbomolecular pump. The rotor assemblycomprises a rotor shaft, a plurality of rotor bladesextending from the rotor shaft, and a balancing memberfitted within the rotor shaftwith an interference fit. The rotor shaftextends along a longitudinal axisabout which the rotor assemblyis configured to rotate. The interference fit is such that the balancing memberis retained in compression by the rotor assembly. The present disclosure also relates to a turbomolecular pumpincluding the rotor assemblyand a method of assembling a rotor assemblyfor the same.
