NU322-C3 is a cylindrical roller bearing, 110 mm bore × 240 mm OD × 50 mm wide (4.3307 × 9.4488 × 1.9685 in). It has C3 internal clearance.
The NU322-C3 is a single-row cylindrical roller bearing with dimensions of 110mm bore, 240mm outside diameter, and 50mm width. This NU-type bearing features a separable design with the inner ring and roller assembly removable from the outer ring, facilitating mounting and dismounting. The C3 radial clearance provides greater internal clearance than standard, accommodating thermal expansion and shaft deflection.
