Double-row precision cylindrical roller bearings with cage are manufactured in the design NN and NNU. The rolling elements of high precision cylindrical roller bearings are guided between two fixed shoulders that are either positioned on the outer ring (NNU) or on the inner ring (N and NN). IBC high precision cylindrical roller bearings from the NN design only absorb radial forces. They permit unconstrained axial displacement inside the rolling bearing in both directions between the shaft and the housing. W33 = Lubrication Groove And Three Holes In Bearing Outer Ring. Q851 = Smaller Bearing Clearance, M = Machined Brass Cage Located On Rolling Elements. SP = Special Precision Class For Machine Tool Bearings: Dimensional Accuracy Approximately To P5, Running Accuracy Approximately To P4.
