Single Row Cylindrical Roller Bearings With Inner Ring NU 208 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 208 ECM

The NU 208 ECM is a single row cylindrical roller bearing with a 40mm bore and 80mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 13950 lbf and spins smoothly at speeds up to 11000 RPM.

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

With a compact width of 18mm, it fits neatly into tight spaces. The chamfered edges (1.1mm) simplify installation. Compliant with RoHS and REACH standards, it’s a safe choice for various applications.

Ideal for machinery like pumps or gearboxes where radial and axial loads are present. Its interchangeability with SKF bearings makes it a practical replacement option. Weighing 0.43kg, it balances strength and portability.
