Top roller (also called carrier roller, upper roller) is assembled on the crawler frame and hold up the track shoes. It is used to hold up the track shoes assy, make the crawler shoes has a certain tension and keep the crawler track assy straight, and it will not bear a lot of pressure. However, we still insist on using high-quality High manganese steel, and carry out the overall heat treatment to ensure its stability and improve work efficiency.

100% match Floating seals avoid oil spilling

Oil leakage can be said to be the killer that ends the service life of the top roller. Once the lubricating oil leaks, the wear of the copper sleeve will soon be accelerated, and the entire supporting roller will be damaged in a very short time. We strictly control the quality and 100% accurate dimensions of the floating seal, and conduct a running-in test after assembly to verify that the oil seal is working in the correct position, further reducing the possibility of oil leakage.
