Description
Description
SKF Super Precision Double Row Cylindrical Roller Bearings: Double row cylindrical roller bearings SKF super-precision double row cylindrical roller bearings are manufactured as standard in the NN 30 and NNU 49 series. Both series are 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.
Benefits: High-speed capability, high radial load carrying capacity, high rigidity, low friction, low cross-sectional height.
