This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore diameter of 75.0 mm, outside diameter of 160.0 mm, and width of 37.0 mm. The unit weighs 3.2 kg and is fitted with a steel sheet metal cage (JN) and metal shields on both sides. Limiting speed is rated at 5400 1/min, with a reference speed of 5800 1/min, and radial internal clearance falls within the CN (Group N) range. The metal shields keep grease in place and restrict the ingress of solid contaminants, so the bearing is suited for pre-lubricated operation without additional sealing. Standard CN clearance and a steel cage support running at the stated speed ratings under normal shaft alignment conditions. Dimensionally and constructionally, this bearing corresponds to SKF 6315-2Z, NSK 6315ZZ, and NTN 6315ZZ.
