Bearing, pump body assembly and compressor

The invention discloses a bearing, a pump body assembly and a compressor, the bearing comprises a bearing body, the bearing body is provided with a bearing hole, the inner wall of the non-pressure-bearing side of the bearing hole is provided with an oil groove, the oil groove is used for guiding lubricating oil, the bearing body is further provided with a flexible groove, and the flexible groove is an annular groove surrounding the bearing hole; an annular flexible wall is formed between the flexible groove and the bearing hole, and the flexible groove is eccentrically arranged relative to the central axis of the bearing hole, so that the wall thickness of the flexible wall located on the non-pressure-bearing side of the bearing hole is larger than that of the flexible wall located on the pressure-bearing side of the bearing hole. Therefore, even if the depth of the oil groove needs to be increased and the thickness of the whole flexible wall is reduced, under the condition that the thicker part of the flexib
