mini digger undercarriage parts

The track rollers of mini undercarriage parts is to distribute the energy and load of the excavator during work, and to prevent the track and the fuselage from derailing when the excavator is walking. Since most of the track rollers work in sand or harsh working environments, and bear a greater impact force than other components, they are prone to wear, breakage, oil leakage, etc. after a period of work. Therefore, the track rollers must have a very high bearing capacity, wear resistance and sealing. Kyushan load-bearing wheel adopts high-performance oil seal to ensure that the machine runs smoothly and has a stronger seal. With Kyushan's advanced welding and processing technology, the track rollers has a stronger bearing capacity and is more wear-resistant.

The carrier roller excavator, which is also called carrier roller or top roller, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc. Excavator carrier roller excavator is made of roller body, shaft, collars, Bi-metallic Bearings and seal group. It is made by forging, machining, heat treatment, assembly, painting etc. The quality and working life depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. The carrier wheel is located above the X frame, and its function is to maintain the linear motion of the chain rail. If the carrier wheel is damaged, the track chain rail will not be able to maintain a straight line. The carrier wheel is a one-time injection of high-quality oil. It can be replaced with a new one. During the work, try to avoid the rollers being soaked in muddy water for a long time. Usually, keep the X-frame inclined platform clean, and don't let too much dirt and gravel accumulate to hinder the rotation of the rollers.
