Single Row Cylindrical Roller Bearings With Inner Ring NJ 312 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 312 ECM

The NJ 312 ECM is a single row cylindrical roller bearing with a 60mm bore and 130mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 38925 lbf and runs smoothly at speeds up to 7000 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 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 gearboxes or industrial machinery where radial and axial loads are present.

Weighing 2.18kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
