One company has two sets single frame wide 6-rolls cold rolling mill, one is 1450, the other is 1150.
The 1150 type of rolling mill bearing is as follows:
BUR BEARING - FCDP110160560
IMR BEARING - 382940
WR BEARING - FC243390
The 1450 type of rolling mill bearing is as follows:
BUR BEARING - FCDP146206750
IMR BEARING - FC4872220
WR BEARING - FC4464210
Positioning bearing - 86746 86744
FV engineers and the mill maintenance engineers communicate the installation details of roller and roll neck bearings, as well as technical problems in the axial and radial clearance of the bearings. The engineers adjusted the axial clearance of the 1450 rolls of positioning bearing 86744 & 86746, and changed the cage to effectively solve the problem of copper powder wear out of the cage.
