Bearing type and arrangement. Each bearing type has characteristic properties that make it more or less suitable for use in a given application. Matrix 1 gives an overview of the main bearing types (including their major features and design variants) and their degree of suitability for certain aspects of use.
In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load. To reduce the effects of a loose fit, SKF bearings have a helical groove in the bore and/or lubrication ...

Rolling Mill Bearings Rolling Bearings for Roll Neck. 30/09/2019 Four row and double row tapered roller bearings are used in rolling mills. Since they have a loose fit on the neck, the inner ring will inevitably creep on the neck. So the neck will …
Compared with other thrust roller bearings, this type of bearing has a lower friction coefficient, higher speed, and self-aligning ability. 29000 type rollers are asymmetric spherical rollers, which can reduce the relative sliding of rollers and raceways during work, and the rollers are long and large in diameter.
Hydrodynamic roll-neck bearings from SMS group are highly advanced and elementary components of modern rolling mill technology. That's because they support the load-bearing backup rolls. Even under extremely tough operating conditions, they ensure long roll service life and minimal maintenance outlay.

1.1 Four-row tapered roller bearing, KV (TQO) The roll neck bearing used in a rolling mill is limited in its dimensions by the roll neck diameter and minimum roll diameter. The four-row tapered roller bearing is so designed that its load rating may be as large as possible within this limited space. This type of bearing consists of two sets
on the surface of a ball/roller bearing. Peeling can occur when the surface roughness is high, or when the lubrication performance is poor. Peeling has a flat-colored appearance, and when observed under a microscope, shows minute flaking and cracks. The top photo shows an example of minute flaking interconnected with cracks.
The Timken roll neck bearing with an integrated seal can handle difficult working conditions, including high temperatures and speeds, as well as heavy shock loads and misalignment. • Enhanced sealing due to high-performance seal designs with improved contact geometry. • Improved performance in marginal lubrication due to better surface finishes.
