Single Row Cylindrical Roller Bearings With Inner Ring NJ 322 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 322 ECM

The NJ 322 ECM is a single-row cylindrical roller bearing with a 110mm bore and 240mm outer diameter, built from sturdy chrome steel. It handles combined loads up to 119250 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 50mm width and 3mm chamfers, it fits snugly in tight spaces. The inner ring design ensures stability under heavy radial loads.

Ideal for industrial machinery like gearboxes or pumps where high radial and axial loads are present. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF bearings. Weighing 11.9kg, it’s robust for demanding applications.
