The invention belongs to the field of shaft sleeve machining, particularly relates to a production process of a special-shaped oil groove low-resistance rotating shaft sleeve, and aims to solve the problems that an existing special-shaped oil groove low-resistance rotating shaft sleeve is inconvenient to inspect during production, most of inspection depends on naked eyes and is greatly influencedby human factors, the number of unqualified products in unit time cannot be monitored, and the quality of a bearing cannot be guaranteed. According to the following scheme , the production process comprises the following steps that S1, a shaft sleeve material is subjected to acid pickling, and then heat treatment is carried out; S2, an inner hole is drilled in the shaft sleeve material obtained after heat treatment, and then the inner side and the outer side of the drilled shaft sleeve material are polished; and S3, twelve containing grooves are dug in the inner wall of the hole, and the crosssections of the containin
