Double Row Full Complement Cylindrical Roller Bearings NNC 4918 CV

Double Row Full Complement Cylindrical Roller Bearings NNC 4918 CV

The NNC 4918 CV is a double-row cylindrical roller bearing with a 90mm bore and 125mm outer diameter, crafted from durable 52100 chrome steel. Its full-complement design means it has no cage, allowing for higher load capacity.

This bearing handles combined loads, with a dynamic radial load of 36225 lbf and a static radial load of 67500 lbf. It operates smoothly at speeds up to 3000 RPM and works in temperatures from -30°C to 110°C.

The open design simplifies lubrication, accepting both grease and oil. Its double-row construction provides stability, making it suitable for heavy-duty applications.

Ideal for industrial machinery or gear systems where high radial loads are common, this bearing is interchangeable with SKF models. Weighing 1.36kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards.
