What is causing your rolling mill bearings are often damaged?

What is causing your rolling mill bearings are often damaged? 2019 - 06 - 13 in recent period, a lot of people to consult with our mill bearing is bad to do, what causes rolling mill bearing broken? Here the author will briefly analyze the causes of damage of rolling mill bearing is what? Through effective data analysis, the main form of bearing damage to fracture, wear and corrosion. 01 fracture: inner and outer ring fault fracture outer ring, rolling body burst, keep frame fracture is mainly due to the large load, low bearing pressure caused by fracture phenomenon. Inner ring fracture, except under cyclic load during installation in interference fit with roller GengLian meet again, there are tensile stress around, as long as the tiny crack is formed on the inner ring, will soon expand cause inner ring crack fracture. Bearing in addition to the above reason, another reason of the fracture is roll in the oil and gas is in short supply or interrupt, cause bearing heating, in turn, lock, cause inside and outside the circle, cage, roller broken. 02 pitting and wear what cause wear mostly by the roll neck with inner hole in relative rotation. Pitting and there are two main reasons: improper heat treatment of bearing material is unqualified. Roll in contents, bearing pitting corrosion occurred in the process of operation. In addition, due to the improper operation, cause copper stent deformation, roll into the bearing ball and the inner sleeve friction, will be within a set of scratches, the roll is not flexible in running, lead to bearing failure. Mill roll gap height is not consistent on both sides or wrong roll phenomenon is serious, causes the roll force caused by uneven bearing some point during operation, causing bearing failure. （ Luoyang hui)
