Single Row Full Complement Cylindrical Roller Bearings NCF 18/630 V

Single Row Full Complement Cylindrical Roller Bearings NCF 18/630 V

The NCF 18/630 V is a single-row cylindrical roller bearing with a large 630mm bore and 780mm outer diameter, built for heavy-duty applications. Made from chrome steel, it handles combined loads up to 281,250 lbf radially and allows some axial movement.

Its full complement design means it has no cage, maximising roller count for higher load capacity. The open seal type simplifies lubrication with grease or oil, and it operates in temperatures from -30°C to 110°C.

This bearing suits industrial machinery like large gearboxes or presses where high radial loads are common. Weighing 72.5kg, it’s built to last while meeting RoHS and REACH standards. Interchangeable with SKF models for easy replacement.
