This deep groove ball bearing carries radial and moderate axial loads on a single row of balls running in deep-groove tracks. Bore diameter is 90.0 mm, outside diameter 190.0 mm, width 43.0 mm, and net mass 5.5 kg. The bearing is fitted with seals on both sides (2RSR) and uses a steel sheet metal cage (JN), giving a limiting speed of 2170 1/min. Radial internal clearance is CN (Group N), the standard clearance class. The integrated seals keep grease in and contaminants out, so the bearing runs with lifetime lubrication and needs no external sealing arrangement. Standard CN clearance and the steel cage suit it to normal operating conditions without special alignment demands. Dimensionally and constructionally equivalent bearings are SKF 6318-2RS1, NSK 6318DDU, and NTN 6318LLU.
