Double Row Full Complement Cylindrical Roller Bearings NNC 4860 CV

Double Row Full Complement Cylindrical Roller Bearings NNC 4860 CV

The NNC 4860 CV is a double-row full complement cylindrical roller bearing, measuring 300mm in bore diameter and 380mm in outer diameter, with a width of 80mm. Made from durable 52100 chrome steel, it handles combined loads with ease.

Its full complement design (no cage) allows for higher load capacity, supporting dynamic radial loads up to 193050 lbf. It operates smoothly at speeds up to 1000 RPM and works in temperatures from -30°C to 110°C.

The open seal type simplifies maintenance, and it can be lubricated with grease or oil. This model is interchangeable with SKF bearings, making it a practical choice for replacements.

Ideal for heavy-duty applications like industrial gearboxes or large machinery where high radial loads are common. Compliant with RoHS and REACH standards, it weighs 21.5kg for its robust size.
