Single Row Cylindrical Roller Bearings With Inner Ring NU 309 ECM

Single Row Cylindrical Roller Bearings With Inner Ring NU 309 ECM

The NU 309 ECM is a single row cylindrical roller bearing with a 45mm bore and 100mm outer diameter, crafted from durable chrome steel. It handles combined loads up to 25200 lbf and reaches speeds of 8000 RPM.

Its brass cage ensures 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 25mm, it fits well in tight spaces. The chamfered edges (1.5mm) make installation simpler.

Ideal for industrial machinery or gearboxes where radial and axial loads are present. Compliant with RoHS and REACH standards, it’s a practical choice for replacements, especially as it’s interchangeable with SKF models. Weighing 1kg, it balances strength and manageability.
