Single Row Cylindrical Roller Bearings With Inner Ring NU 211 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 211 ECM

The NU 211 ECM is a single-row cylindrical roller bearing with a 55mm bore and 100mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 21712 lbf and reaches speeds of 8000 RPM.

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

With a compact width of 21mm, it fits well in tight spaces. This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for industrial machinery or gearboxes where radial and axial loads are present.

Weighing 0.77kg, it offers a sturdy build without being overly heavy. Compliant with RoHS and REACH standards for safe use.
