The factors that influence the life time of the conveyor roller bearing
The steel material may contain 8 to 20 percent of element Ar after being quenched.
It has both advantage and disadvantage that the conveyor roller bearing contains element Ar, to increase the advantage and cut the disadvantage, it must be appropriate content of the Ar in the conveyor roller bearing.
Because the content of the Ar is mainly related with the condition of quenching, and the Ar will influence the content of carbon, so it is hard to judge the effects on the conveyor roller bearing with the Ar. We research the effects on the hardness and life time of the bearing steel with the content of the Ar. It has different functions with the content of the Ar inside the bearing steel, we must act as different standards.
As the content of the Ar increasing, the hardness and life time of the conveyor roller bearing will increase meanwhile, and reduced after reaching the peak.
In conclusion, the advantage of the element Ar must be its stable state of it. If it changes initiativly, the toughness of the steel will reduce rapidly and the conveyor roller bearing will be tendered.
