The role of track rollers

The track rollers are used to support the weight of the tractor while rolling on the guide rail (rail link) or track surface of the track, and it is also used to limit the track to prevent lateral slippage. The rollers force the track to slip on the ground as the tractor turns.

The track roller is one of the four-wheel belts of the crawler construction machinery chassis. Its main function is to support the weight of the excavator and bulldozer, and let the track move forward along the wheels.

The function of the track roller is to transfer the weight of the locomotive to the ground and roll on the track. In order to prevent derailment, the track roller should also be able to prevent the track from moving laterally relative to it.

Track rollers often work in muddy water and gray sand, and are subjected to strong impacts. The working conditions are extremely harsh, and the wheel rims are easy to wear.

The requirements for track rollers are: wear-resistant rims, reliable bearing seals, and low rolling resistance..
