Puzik E.A., Zhirkin Yu.V., Filatov A.A. Increase in the life of bearing supports of four-high stands during their maintenance

Abstract

This paper focuses on maintenance of four-high rolling stands, gives data on maintenance of such facilities at OJSC MMK, describes the technique for finding the effect of various lubricants on the rolling bearing life, contains calculations to select an optimum viscosity grade of a lubricant to increase the life of the bearing units of facilities under study in certain work conditions.

Keywords

Bearing supports of mill stands, rolling bearing life, maintenance of bearing supports.
