Double Row Full Complement Cylindrical Roller Bearings NNCF 4936 CV

Double Row Full Complement Cylindrical Roller Bearings NNCF 4936 CV

The NNCF 4936 CV is a double-row cylindrical roller bearing with a 180mm bore and 250mm outer diameter, built from tough chrome steel. It handles combined loads up to 133650 lbf and runs smoothly at speeds up to 1000 RPM.

Its full-complement design (no cage) maximises load capacity, 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 gearboxes where high radial loads are common.

Weighing 10.3kg, it’s sturdy yet manageable for its size. Compliant with RoHS and REACH standards for safe use.
