Description:

SOCARE® full complement cylindrical roller bearings
Multi-row full complement cylindrical roller bearings are mainly used in small cold rolling mills where very considerable rolling forces occur but where rolling speed is limited. Other applications for these bearings include straightening machines, shears and extruders. To facilitate efficient lubrication, all multi-row full complement cylindrical roller bearings have lubrication holes, or an annular groove and lubrication holes in the outer ring.

SOCARE® multi-row cylindrical roller bearings are mainly produced to the NNU design described below. To special order, SOCARE® can also produce three to five-row bearings of the NNCL and NNC designs. However, because of the large number of possible designs and sizes NNCL and NNC design bearings are not shown in the product tables. Further information on these bearings will be sent on request.

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

NNCL design
These bearings have four to six integral flanges on the inner ring and a flangeless outer ring. Retaining rings at both sides of the outer ring raceway serve to hold the bearing together. A certain amount of axial displacement of the shaft relative to the housing can take place in both directions inside the bearing.

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