    Abstract: The present invention provides a bearing cage for a rotor bearing of a turbomolecular pump. The bearing cage comprises a plurality of bearing pockets each of which, in use, houses a bearing ball such that the bearing ball operably engages an inner race and an outer race of the rotor bearing. Each bearing pocket of the bearing cage has a primary chamber for housing the bearing ball and each bearing pocket further comprises a sump.

    Abstract: The present disclosure relates to a vacuum pump including a bearing and a lubricant supply system for lubricating the bearing. The lubricant supply system includes: a lubricant reservoir comprising a reservoir matrix for receiving a lubricant; a lubricant transfer arrangement in contact with the reservoir matrix for transferring lubricant from the reservoir matrix to the bearing, the lubricant reservoir including a reservoir enclosure for locating the reservoir matrix in position relative to the lubricant transfer arrangement; wherein the lubricant reservoir includes a plurality of contact regions at which the reservoir matrix is in contact with the reservoir enclosure for locating the reservoir matrix in position relative to the lubricant transfer arrangement and a plurality of spacing regions between respective contact regions at which the reservoir matrix is spaced apart from the reservoir enclosure for receiving gas and lubricant foam caused by outgassing in the lubricant in the reservoir matrix.

    Abstract: An oil feed assembly for a vacuum pump comprises: an oil feeder located for feeding oil to one side of a bearing of the vacuum pump; an oil sump located on the one side of the bearing and configured to receive excess oil from the oil feeder; and a venting bypass conduit fluidly coupled with the oil sump and with another side of the bearing, the venting bypass conduit having an inlet located at an elevated position above a floor of the oil sump and configured to convey gas from the oil sump to the another side of the bearing. In this way, the venting bypass conduit provides an alternative path which allows gas within the oil sump to escape during pump-down while preventing oil within the oil sump from escaping with the gas travelling through the venting bypass conduit.
