The NU209K-C3 is a single-row cylindrical roller bearing with a 45mm tapered bore (1:12), 85mm outside diameter, and 19mm width. The tapered bore design allows mounting directly onto tapered shafts or standard shafts using adapter sleeves. C3 radial clearance provides greater internal clearance than normal, accommodating thermal expansion and misalignment in operating conditions.
Cylindrical roller bearings excel in applications requiring high radial load capacity and moderate speeds, including electric motors, gearboxes, pumps, and machine tool spindles. The NU design features two integral ribs on the outer ring and allows axial displacement of the shaft relative to the housing, making it suitable for free-end bearing arrangements.
