Multirow cylindrical roller bearing
4011
Multirow cylindrical roller bearing is typically used in the necks of the rolls in rolling mills, calenders, roller presses. Its peculiarity is a lower coefficient of friction.
It is highly recommended in high-speed rolling mills due to the fact that it is normally assembled with interference fit.
The reduced radial footprint of this bearing allows the use of high diameter necks with respect to the rolling cylinder diameter.
