The introduction of track roller

The track roller is used to support the weight of the tractor, while rolling on the track roller (rail chain) or track plate surface, it is also used to limit the track, prevent lateral slippage. When the tractor turns, the weight wheel forces the tracks to slip on the ground. The supporting wheel is often in the mud, water and dust, and bear strong impact, so it is required to seal reliable, wear-resistant ring.
