This deep groove ball bearing carries radial and moderate axial loads through a single row of balls running in a steel sheet metal cage (JN). Bore diameter is 75.0 mm, outside diameter 160.0 mm, width 37.0 mm, and net mass 3.076 kg. Radial internal clearance is CN (Group N), the limiting speed is 6300.0 1/min, and the reference speed is 5800.0 1/min. The standard clearance class suits general rotating applications without special preload requirements, and the sheet metal cage keeps the design lightweight while guiding the balls at the stated speed ratings. No integrated seal or shield is specified, so lubrication and contamination protection must be provided externally, matching the open bore type (Z) configuration. Dimensionally and constructionally, this bearing corresponds to SKF 6315, NSK 6315, and NTN 6315.
