excavator spare parts Daewoo Doosan DH55 DX60 Track Roller 2270-1061 bottom roller
Product Description
The track rollers produced by our company are suitable for small excavators and heavy excavators and bulldozers from 0.2-120 tons. The DH55 track roller is a part that requires high wear resistance, so we not only need to carry out quenching and tempering treatment to make its internal structure uniform and fine. The hardness reaches HRC50. And if the wear resistance is not high, we will also carry out through quenching treatment to improve the wear resistance of the track roller and prolong its service life.
