Single Row Cylindrical Roller Bearings With Inner Ring NJ 336 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 336 ECM

The NJ 336 ECM is a single-row cylindrical roller bearing with a 180mm bore and 380mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 229500 lbf and runs smoothly at speeds up to 2000 RPM.

Its brass cage keeps rollers centred for even wear, while the open design allows easy lubrication with grease or oil. The bearing operates reliably in temperatures from -30°C to 110°C.

With a 75mm width and precise tolerances, it fits snugly in heavy-duty applications. Ideal for industrial machinery like gearboxes or compressors where high radial loads are common.

Weighing 43.9kg, it’s built for durability. Compliant with RoHS and REACH standards, it’s interchangeable with SKF bearings for easy replacement.
