Application: Nippon Sharyo DH658 track roller (also called lower roller, bottom roller) is used to support the weight of the crane body and roll on the track shoes so that the machine travels along the tracks shoes. It is also used to hold track shoes so that it does not slip along the transverse direction and forces the track to slip on the floor when turning. In some special load conditions or arm conditions, force only on some track rollers, so the arrangement of track rollers is middle sparse and two ends dense. Because it often work in the mud and other difficult conditions, and bear a strong impact, so it is required to seal reliably, with high strength and stiffness.
