Cylindrical roller bearings
| 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 also appropriate for high-speed applications in that they can be machined very accurately due to their structure. |
| Having a separable inner ring or outer ring, these bearings can be mounted and dismounted easily. |
 Single-row cylindrical roller bearings |
| 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 and NH types can carry a certain degree of axial load in both directions. |
| Type R cylindrical roller bearings feature enhanced load rating compared with standard series, though both have equal dimensions. |
| This is because type R bearings have different interior design. They are identified by supplementary code "R". |

| Double-row cylindrical roller bearings |
| 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". |
| These bearings can accommodate high radial loads, and are often used on machine tool spindles. |
