ABSTRACT:
A roller frame support arrangement for a crawler tractor that includes a hub member secured to the roller frame and having a bore formed therein for receiving one end of an axle shaft. Bushing means are located in the bore and are interposed between the hub member and the axle shaft for absorbing radially directed loading. In addition, the hub member is formed with a radially extending flange located at its outer end that accommodates a disk-type plate fastened to the axle shaft. The disk-type plate has a pair of laterally spaced bearing surfaces for absorbing thrust loads imposed upon the roller frame. An end cap is secured to the flange and together with the latter provides a pair of bearing surfaces for engaging the disk-type plate.
