Deep groove ball bearing 16017 carries radial load on a single row of balls running in a narrow cross-section, 85 mm bore, 130 mm outside diameter, 14 mm width, weighing 0.666 kg. The cage is a steel sheet metal design in JN execution, radial internal clearance falls in CN (Group N), and the limiting speed reaches 7400 1/min with a reference speed of 4400 1/min. The narrow width suits installations where axial space is restricted while radial capacity at this bore size is still required. CN clearance corresponds to normal running conditions without preload, and the steel sheet metal cage keeps ball spacing stable at the stated speed range. As supplied, the bearing is open (no seals or shields fitted), so lubrication and contamination protection must be provided externally, and mounting should account for shaft and housing fits appropriate to a Z bore type.
