NU 228 ECML

Designed for heavy industrial machinery requiring exceptional radial load capacity under high-speed operating conditions, the NU 228 ECML single row cylindrical roller bearing features standardized main dimensions of 140 mm bore diameter, 250 mm outer diameter, and 42 mm width. Built with SKF's optimized "E" design internal geometry, the NU 228 ECML maximizes roller-to-raceway contact area to deliver an impressive basic dynamic load rating of 450 kN and a static load rating of 510 kN. The non-locating NU configuration of the NU 228 ECML incorporates two integral outer ring flanges alongside a flangeless inner ring, accommodating axial thermal expansion of the shaft relative to the housing in both directions while enabling hassle-free mounting through its separable ring structure. Furthermore, the NU 228 ECML utilizes a heavy-duty "ML" window-type machined brass cage that lowers friction, tolerates severe vibration, and enables a high limiting speed of up to 4,800 r/min.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
