Excavator Tracked Roller

Brief Introduction 

The gate track rollers are used to support the weight of the tractor while rolling on the track rails (rail links) or track plates, and they are expected be used to restrain the track to prevent lateral slippage. Besides, they are able to restrain the tracks and prevent them from slipping sideways. When the tractor is going to turn around, the heavy duty track rollers will force the tracks to slide on the ground. The supporting wheels are often working in mud, water and dust, so they are always subject to strong impact, which is the reason that they require a reliable seal and wear-resistant rims.

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

The track roller bearing often works in mud, water and sand, and is subject to strong impact, so the working conditions are extremely harsh and the wheel rim is easily worn.

The requirements for the supporting wheel are: the wheel rim is wear-resistant, the bearing seal is reliable, and the rolling resistance is small, etc.
