Single Row Cylindrical Roller Bearings With Inner Ring NU 238 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 238 ECM

The NU 238 ECM is a single-row cylindrical roller bearing with a 190mm bore and 340mm outer diameter, built from tough chrome steel. It handles combined loads up to 180,000 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 55mm width and 4mm chamfered edges, it fits securely in heavy-duty setups. This model is interchangeable with SKF bearings, making it a practical choice for replacements.

Weighing 23.1kg, it’s sturdy enough for industrial machinery like gearboxes or pumps. Compliant with RoHS and REACH standards for safe use.
