Disclosed in the invention is a spacer-bush-contained automotive hub bearing unit comprising a hub, a half shaft, a half shaft casing pipe and a bearing. The half shaft contains a half shaft body and a half shaft end cover arranged at the outer end of the half shaft body. The half shaft casing pipe sleeves the outside of the half shaft body; and the hub sleeves the outside of the half shaft casing pipe. The tail end of the hub and the half shaft end cover are connected by bolts. The bearing located between the half shaft casing pipe and the hub contains an outer bearing and the inner bearing; the inner bearing is arranged at the inner side of the half shaft casing pipe; and the outer bearing is arranged at the outer side of the half shaft casing pipe. A spacer bush is arranged between the inner bearing and the outer bearing; the two ends of the spacer bush are connected with non-basal surfaces of the inner bearing and outer bearing. According to the bearing unit, because the integrated spacer bush is arranged between the small end surfaces of the inner sleeves of the inner bearing and the outer bearing, the original-design-based reasonable and accurate state of the working gap of the bearing can be kept to be unchanged based on the spacer bush.
