Introduction to track rollers
The track roller is one of the chassis accessories of the crawler crane. Its function is to transfer the weight of the excavator to the ground. When the excavator drives on uneven roads, the track roller will be affected by the impact force of the ground, so the load on the track roller is large. The working conditions are harsh, often exposed to dust, and sometimes soaked in muddy water, so good sealing is required. Rollers can be divided into single-sided rollers and double-sided rollers;

Characteristics of track rollers
Excavator rollers and pusher rollers. Excavator rollers are generally made of black oil. The material of track crane rollers is mostly made of 35MN and 5OMN. The wheel surface is fired and the hardness reaches HRC48 or 57 to obtain good wear resistance.

Sliding bearings are often used for support, and floating oil seals are used to prevent dust. Lubricating oil generally only needs to be added once during an overhaul period, which simplifies the daily maintenance work of the excavator.
