Installing the ball cage
If ball cages are used in conjunction with open guide bushes, the ball cage and the guide shaft should run together into the bush. Since undersizing (preloading) is employed, this method is only one that can prevent the balls sliding between the bush and shaft.

In the case of rotary stroke bearings with closed guide bushes, the guide shaft must be inserted against the preloading pressure. Lubrication grease is advisable to prevent the balls becoming flattened.

Particularly in the case of ball cages with larger diameters, it must be ensured that the cage is properly centered in the guide bush.
