An autobalancing unit arranged to produce automatically in a rotary system, with which the unit is associated, a static and/or dynamic balancing effect, and incorporating in combination an outer race ring (2) with a circumferential inner race track (7), an inner race ring (3) positioned in the bore of the outer race ring (2) concentric therewith and having an outer circumferential surface (8) confronting the race track (7) of the outer race ring (2), cover members (4, 5) fitted between the race rings, thereby spacing apart the race rings and sealing of an annular chamber (6) between themselves and the race rings, and a number of rolling bodies (10) positioned in said chamber and being of a diameter smaller than the radial size of the annular chamber (6), whereby the race track (7) of the outer race ring (2) and the rolling bodies (10) have substantially the same hardness and/or yield strength. |
