This deep groove ball bearing carries radial and moderate axial loads on a shaft of 15.0 mm, with an outside diameter of 42.0 mm and a width of 13.0 mm. It is a single row design fitted with metal shields on both sides and a steel sheet metal cage (JN). Net mass is 85.5 g. Limiting speed is rated at 21400.0 1/min, with a reference speed of 17500.0 1/min. Radial internal clearance is CN (Group N). The metal shields keep out coarse contamination while allowing the pre-filled grease to remain in the bearing, so no external sealing is required at installation. Standard CN clearance and the pressed steel cage suit general-purpose rotating applications where shaft alignment is accurate and speeds stay within the stated limits. Dimensionally and constructionally, this bearing corresponds to SKF 6302-2Z, NSK 6302ZZ and NTN 6302ZZ.
