Metallurgical – rolled pipes from 40-72mm

Responsible unit

• Cold rolling mill HPT90 (rolling of stainless steel tubes of different diameters) from 40-72mm diameter.

Problem encountered

• When strikes occur in the rolling of cold rolled tubes (the process of drawing the tube), in the bearing the gap B.E.P. sharply increases as a result of the impact, and sometimes the bearing suffers internal destruction, which leads to the release of rejected tubes during rolling and sometimes to a stop technological process

Our solution

• The improved design of GIB 77752M bearings, specially designed for applications with high impact loads, was installed in the rolls of the cold-rolling mill. Process interruptions were eliminated and the mill returned to normal operation.
