The utility model adopts the technical proposal that:

a high-bearing compact hub bearing unit comprises an outer ring and an inner ring, wherein a roller pin is arranged in a retainer, a through groove is axially formed in the outer ring, the inner ring is arranged in the through groove, the retainer is arranged between the outer ring and the inner ring, a first roller path in rolling fit with the roller pin is arranged on the inner wall of the through groove, a second roller path in rolling fit with the roller pin is arranged on the outer wall of the inner ring, the high-bearing compact hub bearing unit further comprises a connecting ring for butting with a loader, and the connecting ring partially extends into the through groove to be in clamping fit with the inner wall of the through groove.

The inner ring comprises a first inner ring and a second inner ring which are arranged in a mirror image mode.

The first inner ring and the second inner ring are coaxially arranged.

The first inner ring and the second inner ring are connected by a fastener.

The fastener includes the ring body, first inner circle inner wall is equipped with first recess, second inner circle inner wall is equipped with the second recess, be equipped with first flange and second flange on the ring body, first flange withhold in the inboard lateral wall of first recess, the second flange withhold in the inboard lateral wall of second recess.

And two sealing rings are also arranged between the outer ring and the inner ring and are correspondingly arranged on the front side and the rear side of the retainer.

And the outer ring is connected with a bolt.

The utility model has the advantages that: the utility model provides a high compact wheel hub bearing unit that bears is equipped with in its outer lane and is used for the connecting ring of being connected with the loading, does not also influence the assembly when having higher ability of bearing.
