20FC14120 KOYO Cylindrical roller bearings

KOYO Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact. These bearings are suitable for applications

that involve heavy radial and impact loading. They are appropriate for high-speed applications in that they can be machined very accurately due to their

structure. The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft’s axial movement, to a certain extent, relative

to the housing position. The NJ and NF types carry axial load in one direction, while the NUP type can carry a certain degree of axial load in both directions.

Double-row cylindrical roller bearings come in two types : with a cylindrical bore, and with a tapered bore. As for those with a tapered bore, the specified amount of clearance can be

obtained by adjusting the press-in distance. Some bearings have lubrication holes and lubrication grooves on the outer ring. They are identified by supplementary code “W”.
