Construction Machinery Track Roller, designed specifically for heavy-duty tracked construction machinery such as excavators, bulldozers and tracked loaders, is a core load-bearing component of the chassis travel system. Its main function is to support the total weight of the equipment, guide the track to move stably along the travel direction, and withstand impact loads and abrasive wear from the track, ensuring stable walking of the equipment under heavy-duty and harsh working conditions such as mines and construction sites. The roller body is made of high-strength alloy steel/cast steel, integrally formed by forging/casting process with dense and defect-free blank structure, and its strength and toughness are far better than those of ordinary carbon steel parts. The raceway surface is treated with high-frequency quenching + precision polishing, with high hardness and excellent wear resistance, which can effectively resist heavy loads, abrasive wear and impact, greatly extending the service life. The shaft body is forged from high-quality alloy steel and quenched and tempered, with strong fatigue and impact resistance, not easy to deform or crack, adapting to the long-term high-intensity operation requirements of the equipment.
The surface of the track roller is treated with yellow anti-corrosion spray paint with strong adhesion, excellent weather resistance and corrosion resistance, which can effectively resist moisture, dust, rain and corrosive media, preventing performance degradation caused by rust and extending the service life of the product. The internal adopts advanced floating seal + labyrinth seal structure, with high-quality oil seals and long-life grease, which can effectively prevent sediment and sewage intrusion and grease leakage, ensuring long-term stable operation of the track roller and greatly reducing equipment maintenance frequency and costs. The installation dimensions of the product are completely consistent with the original parts, which can be directly replaced without additional modification, greatly reducing equipment downtime. We support customizing track rollers of different specifications and applicable models according to customer needs, and can also provide OEM labeling services, adapting to various tracked construction machinery models. At present, this model of track roller is in stock, which can quickly respond to orders and provide stable supply guarantee, making it an ideal accessory for the maintenance and repair of construction machinery in mining, construction, water conservancy and other fields.
