NU216-C3 is a cylindrical roller bearing, 80 mm bore × 140 mm OD × 26 mm wide (3.1496 × 5.5118 × 1.0236 in). It has C3 internal clearance.
The NU216-C3 is a single row cylindrical roller bearing with 80mm bore diameter, 140mm outside diameter, and 26mm width. This NU-series bearing features a separable design with the inner ring and roller assembly separable from the outer ring, facilitating mounting and dismounting. The C3 radial clearance specification provides greater internal clearance than standard, making it suitable for applications with thermal expansion or shaft deflection.
