The invention relates to a method for producing balls, especially for ball pivots, and to a ball element for two-part ball pivots.

Each marker (50) includes ball portions (58, 60) and socket portions (62, 64) that receive the ball portions (58, 60).

On the left and right end portions of an axle body (30) are pivotably provided knuckles (38) with vertical shaft bodies (35) in between, and steering wheels (4) are installed on the knuckles (38).

The supports may be balls or sockets.

When the ballbar equipment is loaded, the machine tool automatically follows a predetermined controlled-motion pattern for a ballbar test.

Disclosed relates to easy assembling metal balls that are connecting balls between magnetic sticks 20 generally used as magnet play toys.

This makes the circulation of the balls (3) smooth.

The ballbar socket head (302) is then engaged with a telescopic ballbar attached to a base socket (308).

The invention concerns acetabular cups for prostheses.

POT BEARINGS WITH UPLIFT RESTRAINTS: Cosmec can design Pot Bearings with uplift restraints when some uplift is anticipated.

At least one proximal portion (105a) of the arm (105) consists of a series of balls (108) and alternately arranged cylindrical members (109) forming ball sockets.

The two ends of the arch (16) rest on ball joints which are fixed to the ground.

As a result, the complexity of the method is reduced and the problem of dents which can occur on the ball surfaces during tempering is removed.

The seat assembly (1) comprises a seat (10) coupled to panel swivel mountings (9) and seat swivel mountings (8) connected through swivel arms (14).
