The FAG NUP228-E-M1-C3 is a high-capacity single row cylindrical roller bearing designed for heavy radial loads and high speeds. Manufactured by FAG (part of Schaeffler), this genuine bearing features a 140mm bore diameter, 250mm outer diameter, and 42mm width. It incorporates an increased capacity 'E' design, a robust machined brass cage ('M1') guided by the outer ring, and C3 internal clearance, indicating a radial internal clearance greater than normal. The NUP design includes two integral flanges on the outer ring and one integral flange on the inner ring, plus a loose flange washer, allowing for axial displacement in one direction. This bearing is ideal for industrial machinery, gearboxes, and pumps where robust performance and durability are critical.
