Double Row Full Complement Cylindrical Roller Bearings NNC 4960 CV

Double Row Full Complement Cylindrical Roller Bearings NNC 4960 CV

The NNC 4960 CV is a double row full complement cylindrical roller bearing with a 300mm bore and 420mm outer diameter, built from tough 52100 chrome steel. It handles heavy radial loads up to 378000 lbf and runs smoothly at speeds up to 1000 RPM.

Its full complement design maximises load capacity without a cage, while the open seal allows easy lubrication with grease or oil. The bearing operates reliably in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, making it a practical choice for replacements. Ideal for heavy machinery or industrial equipment where high radial loads are common.

Weighing 52.9kg, it’s a robust solution for demanding applications. Compliant with RoHS and REACH standards for safe use.
