Single Row Cylindrical Roller Bearings With Inner Ring NUP 238 ECML

Single Row Cylindrical Roller Bearings With Inner Ring NUP 238 ECML

The NUP 238 ECML 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 180000 lbf and runs smoothly at speeds up to 3000 RPM.

Its PA66 cage keeps rollers centred for even load distribution, while the open design allows easy lubrication with grease or oil. The bearing performs well in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy machinery or industrial gearboxes where high radial and axial loads are present.

Weighing 22.6kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use in various applications.
