Single Row Cylindrical Roller Bearings With Inner Ring NJ 2309 ECP

Single Row Cylindrical Roller Bearings With Inner Ring NJ 2309 ECP

The NJ 2309 ECP is a single-row cylindrical roller bearing with a 45mm bore and 100mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 36000 lbf and reaches speeds of 8000 RPM.

Its open design allows for easy lubrication with grease or oil, while the PA66 cage ensures smooth operation. The bearing performs reliably in temperatures from -30°C to 110°C.

With a 36mm width and 1.33kg weight, it’s compact yet robust for its size. The inner ring design helps with axial displacement up to 3.2mm.

Ideal for industrial machinery or gearboxes where high radial loads and moderate axial shifts are common. Compliant with RoHS and REACH standards for safe use.
