Excavator & Dozer Undercarriage Part Track Roller(Bottom Roller) For Volvo EC290LC/EC290B LC 1181-00781
Function and requirements
The function of the roller is to transfer the weight of the locomotive to the ground and roll on the track. In order to prevent derailment, the roller should also be able to prevent the track from moving laterally relative to it.
The roller often works in muddy sand, and it is subjected to strong impact. The working conditions are extremely bad and the rim is easy to wear.
The requirements for the roller are: rim wear, reliable bearing seal, and low rolling resistance.
Features and advantages
◎ Quality Guarantee
--Mechanical, chemical and microstructure test
--Test with flaw detector after rough machining
--Completed quality control system
--Long warranty time
◎ The shell made by hot forging treatment obtains superior structure of internal materials and fiber
◎ Differential quenching or feed-through quenching heat treatment is effective in crack resistance.
