Single Row Cylindrical Roller Bearings With Inner Ring NJ 220 ECJ

Single Row Cylindrical Roller Bearings With Inner Ring NJ 220 ECJ

The NJ 220 ECJ 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 64125 lbf and runs smoothly at speeds up to 4000 RPM.

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

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy-duty applications like industrial gearboxes or machinery where radial and axial loads are present.

Weighing 3.55kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
