Single-row Cylindrical Roller Bearings

Cylindrical Roller BearingsFeatures：The rollers in cylindrical roller bearing are spaced by the cage, to ensure the rollers stay in the position during rotation and to avoid friction between rollers, effectively avoid the increase of the rotational torque.Accordingly to the different number of roller set, cylindrical roller bearing are divided into single-row, double-row and multi-row structure. The most widely used is the single-row and double-row.There are different types designated as N,NU,NJ,NF,NUP,NH (for single-row bearings), NNU and NN (for double-row bearings depending on the design or absence of side ribs).Applications：Machine Tools, Motorcycles, Railways, Gearboxes.Single-row cylindrical Roller BearingsModelNameFeaturesNCylindrical rollerbearings without outer ring ribsAxial loads can be sustained, can not limit the axial displacement of shaft and housing.Often used as free-end bearings.NUCylindricalroller bearings without inner ring ribsSame as above.NJCylindrical rollerbearings with single inner ring ribsSmall axial loads from one direction can be sustained,and limiting the one direction displacement of shaft and housing. Normally used in pairs.NUPCylindrical rollerbearings with single inner ring ribs and loose ribsOne side of inner ring with single rib, another side with loose rib. Axial loads in both directions canbe sustained, limit the both directions displacement of shaft and housing.   Suitable to be used for fixed-end bearings. Used in the conditions with small bearing installation space.
