Single Row Cylindrical roller bearing with cage 220x400x65 mm NJ244 NUP244 N244
About Cylindrical roller bearings:
1. heavy radial and impact loading
2. less coefficient of friction
3. variations of structure
4. row cylindrical roller bearing feature high radial load because the rollers and raceway are in linear contact
5. The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft
axial movement,to a certain extent, relative to the housing position
6. The NJ and NF types carry a certain degree of axial displacement in both directions so they are also used as free side bearings

N/NJ/NF/NUP Type:
N typebearing housing washer no guard, both sides of the inner ring has guard. Can allow shaft relative bearing between the axial two direction of displacement. NU type of bearing's outer two guard, inner ring no guard. Can also allow shaft relative bearing between the axial two direction of displacement. Therefore, this kind of structure is suitable for use as a floating end bearing.
NJ typebearing housing washer two guard, the inner ring of the unilateral have guard. May have a certain amount of unilateral axial load.
NF typeof unilateral have outer rim, the inner ring of the two guard. Also can bear a certain amount of unilateral axial load. Therefore, this kind of structure is suitable for single direction as the axial location bearing with.
NUP typebearing outer is two guard, inner ring side band (fixed) single guard, and the other side is separable flat ring. May have a certain amount of two-way axial load.
