Single Row Cylindrical Roller Bearings With Inner Ring NU 318 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 318 ECM

The NU 318 ECM is a single-row cylindrical roller bearing with a 90mm bore and 190mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 82125 lbf and runs smoothly at speeds up to 4000 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 43mm width and chamfered edges, it fits snugly in tight spaces. Ideal for heavy-duty applications like gearboxes or industrial machinery where radial and axial loads are present.

Weighing 6.03kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF bearings.
