Single Row Cylindrical Roller Bearings With Inner Ring NU 218 ECML

Single Row Cylindrical Roller Bearings With Inner Ring NU 218 ECML

The NU 218 ECML is a single-row cylindrical roller bearing with a 90mm bore and 160mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 46800 lbf and runs smoothly at speeds up to 8000 RPM.

Its brass cage design ensures stability, while the open construction allows easy lubrication with grease or oil. The bearing operates well in temperatures from -30°C to 110°C.

With a chamfer dimension of 2mm, it fits securely in tight spaces. Ideal for heavy-duty applications like industrial gearboxes or machinery where radial and axial loads are present.

Weighing 2.56kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF bearings.
