Products Description
NN 30 series bearings have three integral flanges on the inner ring and no flanges on the outer 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 NN 30 series can provide a unique balance between load carrying capacity, rigidity and speed.
