Product Description
This Bottom roller (track roller) apply to HYUNDAI MINI EXCAVATOR R55-3 R55M R55MVP R500, R550-3 R555M, R555MVP.
The lower roller is used to support the weight of the tractor and roll on the track guide rail (track link) or track board. It is also used to limit the track and prevent lateral slippage. When the tractor turns, the roller forces the track to slide on the ground.
It often works in muddy water and ash sand, and bears strong impact. The working conditions are extremely bad, and the rim is easy to wear.
The requirements for the roller are wear-resistant rim, reliable bearing sealing and small rolling resistance, etc.
There are some tips for new lower roller installation:
1. Mixing new and old track rollers on the same side can overload the new ones as they sit lower than the worn ones, therefore taking a lot of extra weight.
2. If not replacing all new bottom rollers, it is recommended to fit all the better half on one side and all new ones on the other side. This keeps even pressure on each roller without overloading individual ones.
3. When replacing new roller, do not travel long distances without stopping the machine frequently as they could overheat and seize. Stop every 4-5 minutes and go the opposite direction a little to help circulate the oil. This is standard precaution for the first 100 hours.

1. Through quench-tempering processes to guarantee excellent mechanical properties, high strength and superior wear resistance to bending and breakage.
2. Good quality to reduce wear and prolong life-span, adding value to your products further to your business by maximizing durability of your products.
3. Precise design, carefully manufactured for proper fix easy grousering heavy loaded capacity up to 50tons without compromising proper functioning of the excavator reliable quality, high performance, quality services. Our products, your best choice.
