In consideration of lightness, the track material of this embodiment is selected from high-strength aluminum alloy. For strength considerations, aluminum alloy materials sufficient to withstand a weight of 250KG should be selected.

As shown in Figure 1 and Figure 2, the two tracks are parallel to each other, and the lengths of the two tracks are equal, and the front part of the upper surface of each track is made into a U-shaped long groove 5, and a place card is arranged under the rear section of the track. Groove 10 is smooth rail 6 above the trailing end of track. Bearings are installed in the slots. The length of each track in this embodiment is 1695mm, and the length of the long groove for installing the bearing is 1345mm. The long groove with a length of 1345mm is enough to make the thrust pad completely break away from the oil groove window.

As shown in Figure 1, there are a total of thirteen sets of bearings, two bearings in each set, a total of twenty-six bearings, respectively installed in the long grooves on the upper surface of the two rails, and evenly distributed in the long grooves on the upper surface of each rail Thirteen bearings are installed.
