Double Row Full Complement Cylindrical Roller Bearings NNCL 4980 CV

Double Row Full Complement Cylindrical Roller Bearings NNCL 4980 CV

The NNCL 4980 CV is a double-row cylindrical roller bearing with a 400mm bore and 540mm outer diameter, built for heavy combined loads. Made from durable 52100 chrome steel, it handles radial loads up to 544500 lbf and operates smoothly at 1000 RPM.

Its full-complement design (no cage) maximises roller count for higher load capacity, while the open seal allows easy lubrication with grease or oil. The bearing works in temperatures from -30°C to 110°C.

With a 140mm width and 4mm chamfer, it fits securely in industrial setups. The design permits up to 7mm axial displacement, useful in machinery with slight misalignment.

Ideal for heavy equipment like presses or large gearboxes where high radial loads are common. Compliant with RoHS and REACH standards, it’s interchangeable with SKF models for easy replacement.
