Description SOCARE® full complement cylindrical rollerbearings

Multi-row full complement cylindrical roller bearings are mainlyused in small cold rolling mills where very considerable rolling forces occurbut where rolling speed is limited. Other applications for these bearingsinclude straightening machines, shears and extruders. To facilitate efficientlubrication, all multi-row full complement cylindrical roller bearings havelubrication holes, or an annular groove and lubrication holes in the outerring.

SOCARE® multi-row cylindrical roller bearings are mainly producedto the NNU design described below. To special order, SOCARE® can also producethree to five-row bearings of the NNCL and NNC designs. However, because of thelarge number of possible designs and sizes NNCL and NNC design bearings are notshown in the product tables. Further information on these bearings will be senton request.

NNU design
The bearings have two loose flange rings on theouter ring, a flangeless inner ring and four rows of rollers or eight rows ofrollers. The bearings are separable and enable a certain amount of axialdisplacement of the shaft relative to the housing in both directions to takeplace within the bearing.

NNCL design
These bearings have four to sixintegral flanges on the inner ring and a flangeless outer ring. Retaining ringsat both sides of the outer ring raceway serve to hold the bearing together. Acertain amount of axial displacement of the shaft relative to the housing cantake place in both directions inside the bearing.

NNC design
Thesebearings have four to six integral flanges on the inner ring and one integralflange ring and a loose flange ring on the outer ring attached to the outer ringwhich holds the bearing together. These bearings are able to axially locate ashaft in both directions.
