Single Row Cylindrical Roller Bearings With Inner Ring NJ 2308 ECPH

Single Row Cylindrical Roller Bearings With Inner Ring NJ 2308 ECPH

The NJ 2308 ECPH is a single row cylindrical roller bearing with a 40mm bore and 90mm outer diameter, crafted from sturdy chrome steel. It handles combined loads up to 29025 lbf and reaches speeds of 10000 RPM.

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

With a 33mm width and 0.95kg weight, it’s compact yet robust for industrial use. The inner ring design ensures stability under axial displacement up to 2.9mm.

Ideal for heavy machinery or gearboxes where radial and axial loads are present. Compliant with RoHS and REACH standards, it’s a practical choice for replacements, interchangeable with SKF models.
