Single Row Cylindrical Roller Bearings With Inner Ring NJ 219 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NJ 219 ECM

The NJ 219 ECM is a single row cylindrical roller bearing with a 95mm bore and 170mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 57375 lbf and operates smoothly at speeds up to 5000 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. Suitable for heavy-duty applications like industrial gearboxes or machinery where radial and axial loads are present.

Weighing 3.38kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards for safe and eco-friendly use.
