Double Row Full Complement Cylindrical Roller Bearings NNCF 4960 CV

Double Row Full Complement Cylindrical Roller Bearings NNCF 4960 CV

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

Its full complement design eliminates the cage, allowing more rollers for higher load capacity. The open seal type simplifies lubrication, whether using grease or oil.

This bearing handles combined loads and axial displacement up to 6mm, making it versatile for tough conditions. It works well in temperatures from -30°C to 110°C.

Ideal for industrial machinery like gearboxes or heavy equipment where high radial loads are common. Compliant with RoHS and REACH standards, it’s a reliable choice for replacements, interchangeable with SKF models. Weighing 52.1kg, it’s built for durability in demanding applications.
