This deep groove ball bearing carries radial and moderate axial loads on a single row of balls running between an inner and outer ring, with a bore of 85.0 mm, outside diameter of 180.0 mm, and width of 41.0 mm. The net mass is 4.38 kg, and the limiting speed is 2350.0 1/min. It has seals on both sides, a steel sheet metal cage (JN), and radial internal clearance in class CN (Group N). The integrated seals keep grease in and contaminants out, so the bearing runs sealed for life without external relubrication. The CN clearance suits standard operating conditions without added preload requirements, and the steel sheet metal cage guides the balls reliably up to the stated limiting speed. Dimensional equivalents are SKF 6317-2RS1, NSK 6317DDU, and NTN 6317LLU.
