Single Row Cylindrical Roller Bearings With Inner Ring NJ 318 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 318 ECM

The NJ 318 ECM is a single-row cylindrical roller bearing with a 90mm bore and 190mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 82125 lbf and spins 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 reliably in temperatures from -30°C to 110°C.

With a 43mm width and 6.13kg weight, it’s robust yet manageable for industrial use. The inner ring design ensures stable axial displacement up to 2.5mm.

Ideal for heavy machinery, gearboxes, or pumps where combined radial and axial loads are common. Compliant with RoHS and REACH standards for safe operation.
