Single Row Cylindrical Roller Bearings With Inner Ring NU 228 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 228 ECM

The NU 228 ECM is a single-row cylindrical roller bearing with a 140mm bore and 250mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 101250 lbf and runs smoothly at speeds up to 3000 RPM.

Its brass cage keeps rollers centred for even load distribution, while the open design allows easy lubrication with grease or oil. The bearing operates well in temperatures from -30°C to 110°C.

With a width of 42mm and chamfered edges, it fits snugly in tight spaces. This model is interchangeable with SKF bearings, making it a practical choice for replacements.

Ideal for heavy-duty applications like industrial gearboxes or machinery shafts where radial and axial loads are present. Weighing 9.41kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
