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.

but use a longer roll. Bearings in the 86 series can accommodate higher loads in the same mill housing size and can be cost effective but use a longer roll and have higher roll neck stresses. Once a size is determined, check that the minimum acceptable roll diameter (Emin) is equal to or below the minimum backup roll diameter for the mill.

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.
