This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, guided by a steel sheet metal cage (JN). It has a bore diameter of 25.0 mm, outside diameter of 47.0 mm, and width of 12.0 mm, weighing 79.0 g. Both sides are fitted with metal shields (2Z), and internal clearance falls within the CN (Group N) range. The limiting speed is 18600 1/min, with a reference speed of 15200 1/min. The metal shields protect the internal geometry from dust and coarse contamination while retaining factory-applied grease, making relubrication unnecessary under normal conditions. Standard CN clearance and cage type JN suit general rotating shaft applications where consistent radial guidance and moderate speeds are required. Dimensional and constructional equivalents include SKF 6005-2Z, NSK 6005ZZ, and NTN 6005ZZ.
