Disclosed is a spacer bush (8), comprising an inner spacer bush (2) and an outer spacer bush (1) which are in a threaded connection, wherein a plurality of threaded holes (21) in a radial arrangement are provided on the inner spacer bush in a circumferential array, a plurality of waist-shaped grooves (12) extending in the axial direction are provided on the outer spacer bush in a circumferential array, locking screws (3) adapted to the threaded holes are arranged between the outer spacer bush and the inner spacer bush, and the locking screws are restrained and mounted in the corresponding waist-shaped grooves. Further disclosed is a hub unit using the spacer bush. By means of the hub unit, the technical problem of having difficulty in adjusting a bearing play of a traditional hub unit is solved, such that the operation of adjusting the bearing play in the hub unit becomes simple and convenient and highly precise, thereby not only increasing service life of the hub unit, but also increasing assembly efficiency of the hub unit and facilitating daily maintenance. |
