The track roller is one of the four wheels and one belt of the crawler-type engineering machinery chassis. Its main function is to support the weight of the drilling rig and allow the track to move along the wheel. The main structure of the track roller is composed of the wheel body, track roller shaft, bushing, sealing ring, end cover and other related parts.

The track roller is fixed under the wheel frame with screws to support the weight of the machine and distribute the weight on the track plate. At the same time, it also relies on its roller flange to clamp the chain track to prevent the track from slipping (derailing) laterally, ensuring that the machine moves along the track direction.

As the main load-bearing structural component of crawler drilling rigs, especially in large-tonnage crawler drilling rigs, the design and manufacturing quality of the track rollers are directly related to the overall safety of the drilling rig.
