This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 45.0 mm, outside diameter of 75.0 mm and width of 23.0 mm. It weighs 342.0 g and is rated for a limiting speed of 4950.0 1/min. The bearing has seals on both sides, a steel sheet metal cage (JN), and radial internal clearance in group CN. The integrated seals keep grease in and contaminants out, so the bearing runs without external maintenance once mounted. Radial internal clearance CN suits standard mounting conditions without significant shaft or housing preload. Equivalent designations for this size and design are SKF 63009-2RS1, NSK 63009DDU and NTN 63009LLU.
