for Construction Machinery

1. What is a roller?
Supporting wheels occupy a pivotal role in construction machinery, not merely underpinning the machine's weight but also guaranteeing its stable mobility and efficient functionality. When it comes to selecting and maintaining these wheels, particular emphasis must be placed on their wear-resistance, sealing integrity, and rolling resistance specifications, to ensure the sustained and dependable operation of construction machinery.

2.Advantages/Features

High Quality:

The floating oil seal we utilize is meticulously crafted from chromium aluminum alloy boasting high hardness and exceptional wear resistance. Coupled with elastic rubber O-rings, it further enhances the track surface's durability through advanced medium frequency quenching technology. Every intricate detail is engineered to withstand the rigors of time.

High Precision:

The axis is meticulously crafted from premium 45# round steel material, which undergoes rigorous dual heat treatment processes, including quenching and intermediate frequency surface quenching. This results in a surface hardness ranging from HRC52-60, with a hardness layer penetrating 3-6 millimeters deep. This demonstrates remarkable comprehensive performance, and every meticulously engineered detail underscores our relentless pursuit of precision.

Long Lifespan:

After precise welding, the supporting wheel body undergoes rigorous machining on a vertical CNC lathe, ensuring impeccable concentricity of the inner ring. Compared to the traditional method of precision machining and welding half wheel bodies, this process guarantees more uniform contact within the wheel body, mitigating the risk of rapid localized wear. Consequently, the product's service life is significantly extended, providing you with unparalleled peace of mind and reliability.
