Cylindrical Roller Bearing Description
Cylindrical bore and the conical bore two structures. This kind of bearing has a compact structure, rigidity, load capacity, force, deformation, etc, especially suitable for machine tool spindle bearing. It is divided into NN and NNU two structural forms. NN-type bearing a double wall of the inner and outer ring without ribs, NNU type of bearings, compared with a double wall of the outer ring while the inner ring without ribs, the two bearings shall restrict the axis and the relative axial displacement between the housing for non-locating
four-row Cylindrical roller bearing
Four row cylindrical roller bearing and six row cylindrical roller bearings for rolling mill almost all roller neck, roller and rollingpress. Compared with other roller bearing, the bearing friction and low. Since these bearings are mounted with an interference fit on the roll neck, especially suitable for rolling high speed rolling mill application. These bearing low cross section allows the use of relatively large diameter compared with roll roll neck diameter. Due to a lot of roller, the radial load capacity is very high.Multiple row cylindrical roller bearings can only bear the radial load. Therefore, these bearings and deep groove ball bearing or angular contact ball bearings, or radial or thrust tapered roller bearings are installed together design, by the latter under axial load. The four column and six row tapered roller bearings are separate, namely with integral flange of the bearing ring and theroller and cage assembly can be separated type bearing ring mounted separately, or all bearing parts are respectively installed.It was fairly simplified bearing installation, maintenance and inspection. Inner bearing can withstand a certain limit axial displacement of the shaft relative to the bearing seat. Four row cylindrical roller bearing with a cylindrical bore, a number ofdimensions with a tapered bore bearing can also supply. Bearings with a tapered bore can be installed in the process of adjustment, in order to get a certain radial internal clearance or preload.
