This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 90.0 mm, outside diameter of 160.0 mm and width of 30.0 mm. It has metal shields on both sides (designation Z) and a steel sheet metal cage (JN). The net mass is 2.136 kg, limiting speed is 5400 1/min and reference speed is 5100 1/min. Radial internal clearance corresponds to the CN group (normal clearance). The metal shields protect the raceway and balls from coarse contaminants while allowing grease relubrication through the open sides, so the bearing is suited for applications where periodic maintenance is possible. Normal internal clearance (CN) makes it fit for standard shaft and housing fits without special preload requirements, and the steel cage design supports the stated speed limits at the given dimensions. Dimensionally and constructionally equivalent to SKF 6218-2Z, NSK 6218ZZ and NTN 6218ZZ.
