Double Row Full Complement Cylindrical Roller Bearings NNCF 4872 CV

Double Row Full Complement Cylindrical Roller Bearings NNCF 4872 CV

The NNCF 4872 CV is a double-row cylindrical roller bearing with a 360mm bore and 440mm outer diameter, built for heavy loads. Its full-complement design (no cage) boosts radial load capacity up to 210375 lbf, while handling combined loads smoothly.

Made from durable 52100 chrome steel, it withstands temperatures from -30°C to 110°C and speeds up to 1000 RPM. The open seal allows flexible lubrication with grease or oil, making maintenance straightforward.

With a compact width of 80mm and chamfered edges (2.1mm), it fits snugly in tight spaces. Ideal for industrial gearboxes or heavy machinery where high radial loads and axial displacement (up to 6mm) are common.

This model is interchangeable with SKF bearings and complies with RoHS and REACH standards, ensuring reliable performance and safety.
