This cylindrical roller bearing carries a full complement of rollers arranged in two rows, giving high radial load capacity within a compact envelope of 30.0 mm bore, 55.0 mm outside diameter and 34.0 mm width. The outer ring has a central rib and the inner ring has three ribs, forming a locating bearing that fixes the shaft position axially in both directions. Radial internal clearance is CN (Group N), and net mass is 341.25 g. The PP sealing on both sides keeps grease in and contaminants out, allowing the bearing to run without an external seal arrangement. The full roller complement raises load capacity but requires that radial clearance and lubrication be maintained within specification, since there is no cage to space the rollers. Its locating design suits mounting positions where axial fixing of the shaft is required alongside radial support.
