Shaft bearing point and shaft bearing

A shaft bearing, comprising:

• first and second radial bearing points, wherein
• at least one of the first and second radial bearing points comprising:
• a radial bearing in which a drive shaft is rotatably supportable relative to a machine housing,
• wherein the radial bearing is arrangeable directly or indirectly in a machine housing wall which separates a lubricant space from a lubricant-free space,
• wherein in an axial direction, the radial bearing has a lubricant side facing the lubricant space, and a seal side facing away from the lubricant space;
• a radial sealing ring is arranged axially spaced from the seal side of the radial bearing such that, in the axial direction, a lubricant chamber is created between the seal side and the radial sealing ring;
• and
• a chamber partition wall arranged in the lubricant chamber,
• wherein the chamber partition wall divides the lubricant chamber into a bearing chamber, which is arranged between the seal side and the chamber partition wall, and a seal chamber, which is arranged between the chamber partition wall and the radial shaft sealing ring, and
• wherein the bearing chamber and the seal chamber are connected together fluid-conductively via a partition wall choke, wherein the partition wall choke comprises an annular gap as a fluid-conductive connection between the bearing chamber and the seal chamber, said annular gap being formable between the chamber partition wall and the drive shaft and having a through-flow height greater than 0.1 mm and less than 3 mm in a radial direction.
