Snap-in bearing blocks for quick and inexpensive assembly of axle shafts to frames are known, for example, as taught in U.S. Patent 3,389,498. The prior art, however, still requires a sequence of assembling motions in several directions which can easily be accomplished manually, but which is difficult to accomplish using an assembly robot. This disclosure shows a snap-in bearing block and receiving slot which can be snapped-in in a single downward motion performable by a simple robot. As shown in the figure, bearing block 13, which preassembles onto axle shaft 11, has flexible tabs 15, which spread apart as the bearing block is pushed downwardly over the edges 17 of the side frame. The tabs 15 engage locking holes 19 which then hold the bearing block in place in the side frame.
