Lower rollers are a key component of the bottom of crawler tracks of crawler construction machinery, such as excavators and bulldozers. Their main function is to support the weight of the machine and guide the track to run on the correct path, ensuring the stability and reliability of the machine on various terrains.
Lower rollers are usually made of high-strength materials such as steel or cast iron to withstand the weight and pressure of heavy machinery.
To prevent dust, mud and other foreign matter from entering, the lower rollers are designed with good sealing performance, which helps to extend their service life.
