Rolling bearings. Rolling bearings support and guide rotating or oscillating machine elements such as shafts, axles or wheels and transfer loads between machine components. They provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear.

4 neck have a loose fit. As a result, the chocks can be easily removed; their field of application is restricted, however, by the loose fit. If cylindrical roller bearings are fitted as radial bearings, the rolls must be axially supported in an additional axial bearing.
most commonly used Tselikov 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.
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 worldclass brand bearings, such as SKF, TIMKEN bearings, are indeed very beautiful, clean, and they look great in quality.
Kyodo Yushi's products, Roll neck bearing requires a lubrication condition under socalled high PV range since sliding condition between a roller end surface and the flange section of an inner race is very RBG is able to control oil separation through temperature conditions. Providing a function similar to oil lubrication, it contributes to extend service life of a bearing ...
The main features of the Sendzimir mill in structure and performance are as follows: (1) Frame with integral casting (or forging), high stiffness and radial rolling force acting on each section of the frame. (2) The small diameter of the working roll, the high reduction rate of the pass, up to 60%. Some materials can be rolled into very thin ...

In case of prestress split housing, opening value of top mill housing is large and operation characteristics is good. Work roll can be easily and quickly changed, as work roll is of simple shape and without chocks and neck bearings. Changing to new work roll at the last pass of a rolling results excellent strip with splendid surface luster.

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.
