A ball holder (1) for a retainerless saddle (6) having an elongated shaft (2) and a plurality of contact surfaces (3) therearound to hold steel balls (7) in cooperation with a bearing body (4) only when the saddle (6) is withdrawn from a rail (R). The shaft can be made of a hollow tube (41) or a pair of cantilever projections (52 or 62) so that the size of its cross-sectional area can be adjusted. Due to this adjustability, the size of the raceways can also be adjusted to enable to reassemble the steel balls (7) into the saddle (6) at a working site. |
