Single Row Cylindrical Roller Bearings With Inner Ring NJ 2220 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 2220 ECM

The NJ 2220 ECM is a single-row cylindrical roller bearing with a 100mm bore and 180mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 85500 lbf and operates smoothly at speeds up to 4000 RPM.

Its brass cage keeps rollers centred for reliable performance, while the open design allows easy lubrication with grease or oil. The bearing works well in temperatures from -30°C to 110°C.

With a 46mm width and chamfered edges, it fits snugly in tight spaces. Ideal for heavy-duty applications like industrial gearboxes or machinery where radial and axial loads are present.

Weighing 5.63kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a dependable choice for replacements, interchangeable with SKF bearings.
