Excavator parts E35RT track roller

The Bobcat E35RT track roller is one of the key components in the “four wheels and one belt” of the Bobcat E35RT mini excavator chassis. Its main function is to support the weight of the excavator, so that the tracks can roll smoothly on the ground, and at the same time prevent the tracks from slipping off laterally. It usually consists of wheel body, shaft, bearing, sealing ring and other components. The wheel body material is usually made of high-strength alloy steel, which is forged, machined and heat-treated to ensure that it has sufficient hardness and wear resistance. The axle of the supporting wheel requires high machining precision to ensure its matching accuracy with the wheel body and smooth rotation. In the work, Bobcat E35RT supporting wheel is often in the harsh environment of mud, water, dust, and so on, and is subject to greater impact and pressure. Therefore, the sealing and abrasion resistance are highly required.
