The bearing internal clearance has already been set by using the cone spacer, so parts must be combined according to the serial number and matching symbol. The double cup has an oil slot and oil holes. The bearing can carry both radial and axial loads, so it can be used as a fixed-end bearing. It is also used frequently on the free end to relieve the shaft elongation or contraction between the cup and housing.

There are many variations of the bearings: the inner and outer rings can have ribs or not, the inner ring can be in one or two pieces, the bore can be cylindrical or tapered, and other variations. All four-row cylindrical roller bearings only support radial loads, therefore, they must be used in combination with thrust bearings such as angular contact ball bearings or tapered roller bearings.
