When we get a bearing, the first thing we see is the appearance of the bearing. The appearance of the rolling mill bearing is a criterion for judging the quality of the bearing, but it is not the only criterion. The world-class brand bearings, such as SKF, TIMKEN bearings, are indeed very beautiful, clean, and they look great in quality.

Four cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Their friction is low compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.

Wire, rod, and bar mills operate similar to the rolling mills for plate and other product. Operating conditions in these mills tend to subject the bearings to high temperatures, water spray, high loads and marginal sealing arrangements, resulting in short bearing lives [1,2].

Background. Bearings used for steel mill roll necks (Fig. 1) must cope with heavy loads and high-speed rotation, under harsh conditions. In order to respond to these needs, JTEKT is permanently working to resolve related issues, such as developing better bearing materials and improving the bearing seal performance. Figure 1.

most commonly used T-selikov theory. The forces on the roll neck and in the housing posts are identical. The strength of the neck (with a constant relation between its diameter and length) is approximately proportional to d2 Where d = diameter of roll neck bearing. For various mills, roll load depends on the roll material.
