SKF NN3016KTN/SP bearing

80x125x34

with a large quantity of counterfeit SKF bearings, mill manage-ment asked SKF to conduct an inspection. The mill reported that, after two to three hours of operation, the replacement bearings were performing so poorly, so the mill's maintenance team was forced to shut down the machinery, dismount the bearings, and remount the older bearings.
