Carries radial loads and moderate axial loads through a single row of balls running in deep grooves, with a steel sheet metal cage (JN) guiding the ball set. Bore diameter is 85.0 mm, outside diameter 180.0 mm, and width 41.0 mm, giving a net mass of 4.25 kg. Limiting speed is 5000 1/min, reference speed 5300 1/min, and radial internal clearance is CN (Group N). The 85 mm bore with CN clearance suits shaft-and-housing fits without added preload, keeping running clearance within the normal range at rated speed. The pressed steel cage keeps mass low and allows adequate grease flow at the reference speed, making the bearing suitable for grease or oil lubrication in general rotating shaft support where deep groove design accommodates combined radial and light axial loading. Dimensionally and constructionally, this bearing corresponds to SKF 6317, NSK 6317, and NTN 6317.
