1. Double-Row Cylindrical Roller Bearings

Main Specifications

Double-row cylindrical roller bearings of NN30 design have two rows of cylindrical rollers guided by ribs on the inner ring. The outer ring is without ribs. The bearing cannot accommodate axial forces, however bearing design enables mutual bearing rings displacement in both directions within particular limits (see parameter "s" in table of bearings in system section). Double-row cylindrical roller bearings – type NN30K are generally produced with tapered bore, taper 1:12 designated by "K" in suffix (NN30..K). On request also bearings with cylindrical bore can be supplied (NN30). Double-row cylindrical roller bearings are separable. This facilitates mounting and dismounting. Double-row cylindrical roller bearings are characterized by their high rigidity, narrow build-in area, relatively high limit speed and dynamic load rating. Therefore the bearings are predominantly used for spindle arrangements of machine tools and similar machinery.
