P4/P2 grade Zys Good Performance Four-Row Tapered Roller Bearing
Four-row tapered roller bearings are designed to have the highest possible load rating within this limited space. This type of bearing is loosely fitted on the roll neck for easy mounting and disassembly. Accordingly, the roll neck must be lubricated to prevent scoring between the roll neck and bore surface caused by creep. To prevent wear and seizure of the side surfaces of the cone and cone spacer, oil slots are provided on one side of each cone and both sides of the cone spacer. An oil groove and some holes are provided on the double cup and cup spacers.
