Single Row Cylindrical Roller Bearings With Inner Ring NU 2238 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 2238 ECM

The NU 2238 ECM is a single row cylindrical roller bearing with a 190mm bore and 340mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 274500 lbf and runs smoothly at speeds up to 2000 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 92mm and chamfered edges, it fits securely in heavy-duty setups. This model is interchangeable with SKF bearings, making it a practical choice for replacements.

Ideal for industrial machinery like gearboxes or pumps where high radial loads are common. Weighing 38kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
