What are the three parts of the rollers?
这里是标题一h1占位文字
Roller is an important load-bearing component of crawler-type construction machinery (commonly referred to as "lower roller"). The fulcrum is fixed on the trolley frame through the left and right support seats, the wheel body has a press-fitted bushing to rotate with the support shaft, and a sealing assembly is installed between the rotating wheel body and the fixed left and right support seats to keep the support shaft. Sealing with lubricating oil of shaft sleeve and other parts. The sealing assembly consists of a pair of double-cone metal sealing rings and two nitrile rubber fixed compression rings. The rubber ring is installed in the sealing seat of the wheel body and the support seat respectively. Since the metal sealing ring is squeezed by the rubber ring to ensure that its annular land is tightly meshed during rotation, the seal is a floating seal type.
