Rolling mill bearings, is used in metallurgy, mining and other mill roll neck, drum on
the use of bearing. Usually adopts the cylindrical roller bearings under radial load,
deep groove ball bearing or angular contact ball bearings, or radial or thrust design
of tapered roller bearing axial load. Now most of the lubricating oil and gas or oil mist
lubrication way of lubricating and cooling bearing.

Four row cylindrical roller bearing and six row cylindrical roller bearings for rolling
mill almost all roller neck, roller and rolling press. 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 the roller 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 of
dimensions 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.
