What is track roller?
The supporting wheel is used to support the weight of the tractor, while rolling on the track (rail link) or the surface of the crawler track. It is also used to limit the crawler and prevent lateral slippage. When the tractor turns, the rollers force the track to slip on the ground.
The support roller is often in mud, water and dust, and bears strong impacts, so it is required to have reliable sealing and wear-resistant rims
