NU207-C4 is a cylindrical roller bearing, 35 mm bore × 72 mm OD × 17 mm wide (1.378 × 2.8346 × 0.6693 in). It has C4 internal clearance.
The NU207-C4 is a single-row cylindrical roller bearing with dimensions of 35mm bore, 72mm outside diameter, and 17mm width. This NU-type bearing features a single rib on the outer ring and two ribs on the inner ring, allowing axial displacement of the shaft relative to the housing. The C4 radial clearance provides greater internal clearance than standard, suitable for applications with thermal expansion or interference fit requirements.
