Rolling mill bearing characteristics:
1. The maximum dynamic load rating can be achieved with a limited mounting space;
2. They are applicable for high speed operation;
3. They permit more accurate limiting tolerances;
4. Both inner ring and outer ring assembly (outer ring with a set of rollers) are interchangeable, which is helpful for quick roll
replacement;
5. They can only accommodate radial load.

Roller and groove for line contact or repair referrals contact, radial carrying capacity, is designed to withstand heavy load and impact load. Small friction coefficient, suitable for high speed limit speed, close to deep groove ball bearing.
2. But axial movement and can adapt by thermal expansion or installed by the error of shaft and the shell of the relative position of the change, can make free use of the support.
3. The shaft or a hole for processing the demand is higher, bearing outer ring axis after installation to relative skewed kept under strict control, so as to avoid the contact stress concentration.
4. Inner circle or their cups are separable for easy installation, and removal.
5. Stamping steel cage, high-speed bearing or require smooth operation, the use of the bearing entity kept the frame. According to the site and user requirements, also can design and provide with glass fiber reinforced plastic keep frame system.

application
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.
