Product Description

0.2-120 tons of small excavators and heavy excavators, bulldozers can use double flanged track rollers designed by our company, or special versions of track rollers for forestry and agriculture.

The double-code seal design prolongs the service life of the track rollers and greatly improves the wear resistance

The 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.
