This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore diameter of 20.0 mm, outside diameter of 47.0 mm, and width of 14.0 mm. It is fitted with metal shields on both sides and uses a steel sheet metal cage (JN). Net mass is 105.7 g, with a limiting speed of 18700.0 1/min and a reference speed of 16300.0 1/min. The internal clearance is C3 (Group 3), giving greater internal play than standard clearance, which allows the bearing to accommodate thermal expansion and a degree of shaft misalignment during operation. The metal shields protect the raceway and balls from coarse contaminants while retaining the internal grease fill, making this bearing suited for applications requiring low-maintenance operation without contact seal friction. The steel sheet metal cage keeps the balls evenly spaced and supports stable running at the stated speed limits.
