A ball screw device prevents an impression from being formed on a ball screw raceway.

The invention relates to a retaining ring for axially fixing an inner ring on one side in relation to an outer ring of a premounted rolling bearing.

Two raceways (24) disposed opposite each other are designed in each raceway recess (22) for mechanical contact with the rolling bearing (60) guided therein.

A ball screw has a screw shaft, a nut, and balls running in a circulating manner along the ball rolling groove of the screw shaft and the ball rolling groove of the nut.

Two rows of raceways of the ball bearing are formed on the outer peripheral surface of the ball screw nut.

A ball screw assembly having a bearing ball recirculation arrangement.

Each part comprises the treading surface (10) and tightening screws (20).

The invention also relates to the use of such a composition for producing a tread of a tyre with an improved property compromise regarding the grip on wet ground and rolling resistance.

A ball screw device prevents an impression from being formed on a ball screw raceway.

The running wheel also comprises a nut (9) fittingly fixed with the screw.

A ball screw device (23) has a plurality of spiral raceways (61 - 66).

The ball screw (26) has a first and a second raceway (S, K).

The ball screw shaft and ball screw nut are connected through complementary helical grooves filled with ball bearing balls (64).

The arms are mounted to the shoulder clavicles by means of a screw and an axial bearing.

The inventions relate to mechanical engineering, in particular to screw-type gears with rolling elements.
