NU208-C2 is a cylindrical roller bearing, 40 mm bore × 80 mm OD × 18 mm wide (1.5748 × 3.1496 × 0.7087 in). It has C2 internal clearance.
The NU208-C2 is a single row cylindrical roller bearing with dimensions of 40mm bore, 80mm outside diameter, and 18mm width. This NU-design bearing features a fixed outer ring with two integral ribs and an inner ring without ribs, allowing axial displacement to accommodate thermal expansion in the shaft assembly. The C2 radial clearance is less than normal, providing tighter running tolerances for applications requiring reduced internal play.
