D-Series Wear-Resistant Bolts for Doosan DX180 Bulldozers, DX220 Bulldozers - Track Shoe Connecting Bolts, Wear-Resistant and Long-Lasting
The track shoes of Doosan DX180 and DX220 bulldozers rub violently against the ground during operation, which have strict requirements on the wear resistance of connecting bolts. This D-series wear-resistant bolt is made of high-carbon alloy steel, after integral carburizing and quenching treatment, with surface hardness of HRC60-65, and its wear resistance is more than 60% higher than that of ordinary bolts. The thread part of the bolt has been strengthened, and when used with anti-loosening nuts, it can keep tight during frequent movement of the track shoe to avoid falling off. The surface is treated with black oxidation, which not only enhances the rust resistance, but also reduces the friction coefficient with the track shoe, reducing the wear rate. The bolt size is completely compatible with the track shoe mounting hole. After installation, it can effectively improve the overall stability of the track, extend the replacement cycle of the track shoe, and is suitable for high-intensity operation scenarios such as mines and construction sites.
