NNU Series
Classification :
Cylindrical Roller Bearings
PRODUCT DETAILS
NNU 49 series double row cylindrical roller bearings have three integral flanges on the outer ring and no flanges on the inner ring.
It available with either a cylindrical or a 1:12 tapered bore (designation suffix K). In machine tool applications, cylindrical roller bearings with a tapered bore are preferred over bearings with a cylindrical bore, because the taper enables more accurate adjustment of clearance or preload during mounting.
Bearings in the NNU 49 series, with a very low cross-sectional height, provide a higher degree of stiffness than bearings in the NN 30 series, but a somewhat lower load carrying capacity.
