The reasons for the extremely short service life of back-up roller bearing of precision straightening machine are analyzed. The reformation scheme of combining back-up roller and bearing into one set of bearing assembly is proposed. The theoretical analysis and application prove that the service life of complete set of bearing assembly is greatly Improve, significant economic benefits. Figure 5 Figure.
