Single Row Cylindrical Roller Bearings With Inner Ring NJ 2212 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 2212 ECM

The NJ 2212 ECM is a single row cylindrical roller bearing with a 60mm bore and 110mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 32850 lbf and operates smoothly at speeds up to 8000 RPM.

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

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

Weighing 1.26kg, it balances strength and manageability. Compliant with RoHS and REACH standards for safe use.
